Details for all the connectors required can be found by downloading the file to the left.

Please contact our sales team if you have any questions.

How do I use the RS232 on the new V2 Design Studio?

The RS232 works using three elements, one hardware element (Serial COM Port) and two function element (RS-232 Receive and RS-232 Send).

Within the hardware element you must specify standard RS232 properties (baud rate etc.). You must also specify the service type; native if you wish to communicate with another PPA device, Terminal otherwise. The "Terminal Mode" property specifies whether the data should be wrapped with a prompt (easy to use within a terminal) or should be raw (device to device). Then you will need to specify send/receive terminators and separators. The terminator signifies the end of a given RS232 command and the separator is the character used to separate multiple values. 

The RS-232 Send element allows you to specify a serial port (the hardware element) and then numerous "Send Values", this element can be called much like any other action and when it is it will send each value (enclosed within specified pre and post messages) separated via the "Send Separator" specified in the hardware element and ended with the "Send Terminator" specified in the hardware element. The values will be sent in sequential order from top to bottom. 

The RS-232 Receive element allows you to specify a serial port (the hardware element), when this has been selected you will be able to specify an "Alias". In order for an RS-232 Receive to be used it must have a unique identifiable command at the beginning, if no alias is specified then the name of the RS-232 Receive element will be used as the command; if an alias is specified then the Alias will be used as the command. A Receive Separator should follow this and then all values you wish for the device to receive also separated by the Receive Separator and then finished with the Receive Terminator. Then you will specify a list of receive properties/variables, this is where the values will be stored again sequentially from top to bottom as first received to last received. 

For example if the Alias was set to "rx", separator set to comma and terminator set to [CR][LF] and the specified receive value was a text boxes Text property then the following would set the text boxes text value to "Test": 


RS-232 Receive also gives you the option to perform an action once the receive has been completed so you could store a value as a variable and then call an action to display it or modify it with a maths builder before displaying it. 

N.B. we are in the process of creating further tutorial videos to aid in development with new features.

How do I upgrade my device so that it can operate with the new version of the design studio?

Once you have installed the new version of the design studio you will have access to the automatic update feature. This works for both the design studio and the device software.  If you have a device connected that does not have the latest version of device software then you will see a cog icon next to the device. Simply click on this and follow the steps in order to upgrade your device software.

I've been using the BETA software, how do I upgrade to V2?

If you have been using the Beta version of the design studio then you may find that your device software will not upgrade to the V2 device software. In order to get around this you will need to first downgrade your software to the original version:

1) Please download the file "downgrade_to_1678.ppsw" file below:

2) Load up the Design Studio (the latest version is preferable).
3) Connect your device to the computer.
4) Wait for the device to appear in the top right corner of the design studio.
5) Select the options button (three white lines).
6) Select "Upgrade Device Software" from the drop-down menu that appears.
7) Navigate to the file you downloaded "downgrade_to_1678.ppsw" and select it.
8) Select "Upgrade" from the window that appears.
9) Upon completion the pop up window should disappear and the device should now be back to non-beta version.
10) Follow standard steps for upgrading to the new V2 device software.

Is it possible to output 4-20mA from a PanelPilotACE display?

We have found a third party device which converts the PWM output to a 4-20mA output. Take note of selecting the part number on each website. As there are options depending on your specific needs. Most importantly D3 is needed for any part number you choose as the frequency of the Panel Pilot falls in that range. For example, ISO D3-P3-O1-Q01:

I want to implement a spinner that will let me set a variable but I can't find a way to increment the variable. How do I do it?

A maths builder has been added to the Design Studio in V2 of the software to provide this functionality.

How many copies of the Windows software can I install?

The software is free to use and you can install it on as many PC’s as you like. What you’re not allowed to do is sell the software, reverse engineer or modify it in any way. 

Why is the I²C and SPI capabilities of the hardware not available in the software?

Whilst the current software release does not allow you to make use of these our software team is busy adding these features. This feature is our top priority and we expect to make it available in the next few months.

Why does the Panel Pilot ACE software not discover my device on Windows 8?

This is an issue with Windows 8 and requires you to disable driver signature enforcement.  Instructions for doing so can be found in our Installing Panel Pilot Driver On Windows 8 documentation.

Do I need to buy a QT/Digia run-time license?

No, each SGD 43-A is sold with a commercial run-time license from Digia who own the QT platform on which PanelPilotACE runs. You can find more information about this on the Digia website:

My clock is set to the wrong time, how do I set the clock?

Open up the Panel Pilot ACE design studio and connect your device. Assuming your device has connected correctly you should be able to select it in the Device drop down box in the top right of the studio. Click the button to the right of the device selection that looks like three white horizontal lines. From the dropdown menu that appears select "Device Configuration". Then tick the "Set Real Time Clock" check box and ensure the correct time is selected (+1 refers to GMT+1). Hit the configure button and the application will be updated. 

Where is the mounting bracket shown in the data sheet?

The mounting bracket is located in the box below the white tray which holds the SGD 43-A in place. 

The screen on my SGD 24-M goes white when I try to upload an application to it. What can I do?

During the life cycle of our SGD products, there will be unavoidable changes to the display driver chips used in the screens. We always ensure that the latest applications can operate with all display types ever produced (i.e. “backwards compatible”). This means constantly updating the applications to read the driver type and alter display code accordingly.

The SGD 24 series has undergone such a change and to operate it, you need to download the latest version of your chosen configuration. This should happen automatically as you start Panel Pilot or when you click on “Check for updates” in the “Choose Meter Style” box. If this does not work, it might be that your connection to the server is being blocked by a firewall. To remedy this, you can try connecting via a proxy server. Click on File/Proxy Settings. If you still cannot get through, you can download the files directly. Click on the following link to download the .zip file:

Unzip the folder and copy the files into the Resources folder:-

For 32-bit machines: C:\Program Files\Lascar\Panel Pilot\Resources

For 64-bit machines: C:\Program Files (x86)\Lascar\Panel Pilot\Resources

Is there a quick way of testing my projects without having to wire to the SGD 43-A?

The development board (SGD 43-A-DK+ - this includes a display) generates all of the inputs and indicates all of the outputs that are available on the SGD 43-A. Analogue inputs can be varied using dials, digital inputs can be turned on using switches, digital, PWM and alarm outputs are shown by status LEDs. Screw terminals are also available for quick connection of actual signals.

My sensor devices are not communicating with the FilesThruTheAir™ Cloud?

If your access point or WiFi router is working, your device may be out of range. You can check the range of the sensors by pressing the device button three times. This will show a number between 1 and 10 if you have a signal, with 1 being a low signal and 10 a strong signal. When the sensor device shows ‘- -‘, there is no signal.

How do I force a transmission from my WiFi sensor device?

When the sensor is displaying the main reading screen on the LCD, press the button on the front four times. The MAX, MIN and Signal Strength screens will be quickly displayed. The device will try to transmit its latest data immediately, regardless of the transmission rate setting.

If I have a power cut or my WiFi network stops working, will I lose any of my data?

No, even if your WiFi network has failed, the device will continue logging at the sample rate that you have set. When your WiFi network is restored, the device will automatically synchronise data to the Cloud. No data is lost.

The WiFi icon on my sensor is flashing, what does this mean?

This means that the sensor is not connected to the FilesThruTheAir™ Cloud. Check your network connections first and then make sure that the sensor is within range of the access point or WiFi router. To save battery power, the sensor may be in sleep mode for up to 30 minutes and will then look for a connection again. No data is lost while the sensor is temporarily not connected. Once connection is resumed all data will be synchronised with the FilesThruTheAir™ Cloud.

How can I reset my sensor?

The sensor can be reset by holding the button for approximately 10 seconds. Depending on the device model, release the button when either LOW is flashing in the top right hand corner of the display or when ‘r5t’ appears in the middle of the screen. The device will retain all settings but will lose any data that had not been transferred to the FilesThruTheAir™ Cloud. It will continue to be connected to the account it was set-up with and will simply start a new recording session.

Before doing anything after charging up the data logger, always fully factory reset the device before trying to set it up, and after any failed setups. To do this depress the front button for approximately 20 secs until the LCD display reads 'FA5r', then release the button, it will then be fully factory reset. Do not be tempted to release when it gets to approximately 10 secs when the display will change to read 'r5t', make sure you keep the button fully depressed. We do get a lot of customers who release too early and only reset the device! Doing this will return the device to the factory default state, deleting all settings and clearing any remaining data. The device will no longer be connected to any network or FilesThruTheAir™ Cloud account.


What does it mean when the MAX, MIN and battery symbol are all displayed on the LCD at the same time?

This is displayed if the device is charging, and the temperature of the battery is above 40°C. For safety, the device will stop charging until the temperature has returned to a safe level.

How do I turn the sensor off?

The sensor cannot physically be switched off; it will remain on permanently until the battery runs out.

How do I know if my WiFi AP/Router is 802.11b compatible?

All WiFi AP/Routers are 802.11 compatible and there are currently five standards in general use; a, b, g, n and ac. To find out what type of router you have, you may need to refer to your AP/Router user manual or contact your Internet Service Provider or IT Department.

I have connected the device to my PC using the USB cable, but the software does not see it. What should I do?

You can try any or all of these steps to help with this problem:

1) Remove the USB cable and re-insert.
2) Restart the software.
3) Missing Drivers. If this is the case please reinstall the software.
4) Factory reset the device by depressing the front button for approximately 20 secs until the LCD display reads 'FA5r', then release the button, it will then be fully factory reset. Do not be tempted to release when it gets to approximately 10 secs when the display will change to read 'r5t', make sure you keep the button fully depressed. We do get a lot of customers who release too early and only reset the device!

Why will my device not connect to the wireless network?

You can try any or all of these steps to help with this problem:
1) Check that the password being entered is correct.
2) Check that 802.11b is enabled on the access point or router.
3) Ensure MAC filtering is not switched on in the access point or router. If it is switched on, only known devices will be able to connect to your router.
4) Check that your network has an internet connection.
5) Check that the sensor is in range of the router.
6) Check to see if the router has the latest firmware.
7) If the access point or router has WEP Encryption ensure that the HEX key is being entered rather than the password. You can find the HEX key in the internal settings of your access point or router. Alternatively, search the web for resources to help convert your password to a HEX key.
8) Check that DHCP service is running. This allows the sensor device to be allocated an IP Address. Normally, the DHCP service runs in either your router or on a network server. Make sure that the configured DHCP IP address range allows the addition of new devices if not, then extend the range.
9) If your wireless network uses WPA Enterprise, make sure that the correct authentication type is selected from the drop-down box. Only the types listed are supported.
10) If your access point or router has a wireless mode setting, this must be set to ‘Mixed’, not ‘Greenfield’.
11) Make sure that the SSID name does not contain spaces.

If the device battery runs out, will I lose all of my data?

The device will not take readings when there is no power but all readings it has taken prior to the loss of power will be synchronised. Once recharged, the device will reconnect to the FilesThruTheAir™ Cloud, start a new recording session, and continue recording.

If using battery power you must set suitable sample and transmission rates as these will affect your battery life. You can power the device from mains/wall power using a suitable USB power supply if fast transmission rates or long term, uninterrupted logging is needed.

If I have a power outage, will I lose any data?

As the device is powered by battery, the device will always continue recording at the sample rate you have set. If a power outage occurs, the device will continue to attempt to connect to your network until power returns and the access point or router becomes available again. The device then synchronises all remaining data with the FilesThruTheAir™ Cloud. No data is lost.

What battery life can I expect from my sensor devices?


The EasyLog data logging sensors are powered by quality LiPo batteries. The battery life of the sensor is dependent on use.  Transmitting data uses a lot of battery power. By increasing the time between transmissions the battery will last longer. See the table below.

Transmission Period      Typical Battery Life
1 Minute                        1 Month
15 Minutes                     3 Months
1 Hour+                          6 Months+ 

The product will arrive partly charged but you should charge it for 24 hours before use for optimum performance. The battery can be recharged using a PC, a USB wall adapter, or a portable USB battery pack using the USB lead provided. It can also be permanently powered by a USB wall adapter or USB battery pack. Readings may be affected for some sensor types, while the internal battery is being charged. However once charged, continued connection of the charger will have no effect.

Battery life is dependent on a wide range of parameters including:

Transmission period.
Operating temperature. (Lower extremes will have a significant effect).
WiFi encryption method.
WiFi encryption key rotation frequency (determined by the AP/router).
Signal strength between router and WiFi device.
Presence volume and type of WiFi traffic from other devices.
Sample rate.


How do I charge the battery in my sensor device?

The sensor will arrive partly charged but ideally you should charge it for 24 hours before use for optimum performance. The battery can be recharged via a PC, a USB +5V wall adapter, or a portable USB battery pack using the USB lead provided.

Please note that due to the heat generated whilst charging, WiFi devices with an internal temperature sensor will indicate a temperature a few degrees above the ambient temperature. Once fully charged, this heat generation ceases and the sensor will eventually indicate the correct temperature. This anomaly does not apply to data loggers with external temperature probes.

How long will it take to fully recharge my sensor device?

From a very low battery state, it can take up to eight hours to fully charge your sensor. The battery status can be seen from the Devices page on the FilesThruTheAir™ Cloud. The battery can be recharged via a PC, a USB +5V wall adapter, or a portable USB battery pack using the USB lead provided.

Can I permanently power my sensor device?

Yes, you can permanently power the sensor using a USB wall adapter PSU USB-UK, PSU USB-EU and PSU USB-5VDC-US or external battery pack. (both available separately).

Please note that due to the heat generated whilst charging, WiFi devices with an internal temperature sensor will indicate a temperature a few degrees above the ambient temperature. Once fully charged, this heat generation ceases and the sensor will eventually indicate the correct temperature. This anomaly does not apply to data loggers with external temperature probes.

How do I update my devices?

The WiFi devices contain program code that runs internally, often referred to as firmware. You can update the firmware via the FilesThruTheAir™ WiFi Sensor Software (v1.30.41 onwards) by clicking on the green ‘Advanced Tools' icon and then clicking on the green 'Firmware Updater' icon. You’ll need to connect the device to the PC using the USB cable provided then follow the on-screen instructions to download and update the latest firmware versions.  To benefit from the latest improvements we recommend using the latest firmware releases for your devices. Depending on the previous firmware version, your device may be in a factory-reset condition following a firmware update, and will need to be re-connected to the Cloud if being used previously. Any existing data for this device on the FilesThruTheAir™ Cloud will be archived for safe-keeping.

How many sensors can I connect to my FilesThruTheAir™ Cloud account?

The number of sensors you can connect will depend on which type of FilesThruTheAir™ Cloud account you have. This can be the Basic, Personal or Professional accounts.  The Basic account is limited to a maximum of two sensors, whereas the number of sensors that can populate Personal and Professional accounts are limited only by the payment plan selected.  

What does Setup Pending mean?

This means that you have changed a setting on a sensor, for example the transmission rate, an alarm level or any other parameter. The sensor will receive its new settings the next time it transmits to the FilesThruTheAir™ Cloud, hence the set-up will be pending until that time.

Is there a cost associated with using the FilesThruTheAir™ Cloud?

How can I cancel my FilesThruTheAir™ Cloud account?

If you have signed-up with FilesThruTheAir™ directly, you can cancel your account at any time by clicking on the “Account” link and selecting CLOSE ACCOUNT. Your sensor devices will no longer work on the FilesThruTheAir™ Cloud but can still be used in PC only applications.

If this Cloud service has been provided to you by a 3rd party or your supplier, you should contact them directly about cancelling your account.

Can I purchase a FilesThruTheAir™ Cloud account in my country’s currency?

If you have signed-up with FilesThruTheAir™ directly, you can pay in GBP or in USD. If you are not in a country using GBP, we would recommend using USD as your payment method.  If your Cloud service has been provided to you by a 3rd party or your supplier, you should contact them directly about paying for your account.

How can I access the FilesThruTheAir™ Cloud?

You can access your FilesThruTheAir™ Cloud account using any internet enabled device through a web browser. This could be your PC at home/office, your iPad/tablet or your mobile phone, etc. The FilesThruTheAir™ Cloud supports IE11 and above, and the latest Chrome, Firefox and Safari browsers.

Data charges may apply if viewing data from your FilesThruTheAir™ Cloud account on your mobile phone.

Alternatively, you may to use to use the FilesThruTheAir App available for Apple and Android devices.

Where can I find the terms and conditions of the FilesThruTheAir™ Cloud?

You can find links to all our terms and conditions documents at the foot of the 'Welcome to the Cloud' home page.

How secure is my data on the FilesThruTheAir™ Cloud?

Your data on our FilesThruTheAir™ Cloud account is very secure. The only way to access your account and data is to use the email address and password that you specified when signing up to your account. If you have a Professional account with multiple users, a user with Administrator privileges can control which data individuals can access.

We regularly back up all data and take all industry standard precautions. However, we always recommend that you also back up any data locally.


What is the difference between the sample rate and the transmission rate?

The sample rate sets how often the WiFi device records a reading. The transmission rate sets how often the WiFi device transmits this information to the FilesThruTheAir™ Cloud. Choosing the right sample and transmission rate for your specific needs is vital to ensure that you maximise battery life. Every application is different so we have made the system as flexible as possible.

Why have I lost all my data?

The only way sensor data is lost is if you delete a sensor device. The FilesThruTheAir™ Cloud asks if you definitely want to delete the sensor so you will not be able to do this by mistake. If you have a Free account, the FilesThruTheAir™ Cloud stores only the most recent 45 days of data. Data older than this is automatically deleted.

Please be aware that when you highlight a unit on the ‘Devices’ screen and then go to ‘View Data’, only the data from the latest ‘live’ data session will be displayed. You have to click on the ‘Other Sessions’ tab, which will then bring up a list of all the sessions for that device. Just highlight the session you want and click on Graph, Data or Summary to bring up the views for that particular data session.

How do I archive or delete a device?

Select the device(s) and click on “Archive/Delete”. From the options list you may:

1) Archive keep the data but deactivate the device(s), which then cannot be reactivated and will have to be setup again using the latest WiFi Sensor Software
2) Clear keep the device(s) active but delete all of the data.
3) Delete the data and take the device(s) out of use.

Is there an App for the FilesThruTheAir™ Cloud?

Yes, there is indeed a 'Files Thru The Air' App for Apple and Android phones available from iTunes and Google Play Store respectively. Once you have set-up the devices on your Cloud account, the App enables you to monitor your sensors and change settings and parameters in the Cloud whilst on the go.

How often does the sensor device send data to the FilesThruTheAir™ Cloud?

When you first connect the sensor to your FilesThruTheAir™ Cloud account the default transmission period is pre-set to five minutes. You can change the transmission rate by clicking on the sensor you want to change and then clicking on Change Device Settings. The transmission rate setting does not affect delivery of alarm conditions which are transmitted immediately.


Can I try the FilesThruTheAir™ Cloud service before committing to pay for an account?

Our Basic account is perfect for people wanting to trial the FilesThruTheAir™ Cloud with up to two devices. The ability to export reports is limited to paid-for accounts but the Basic account will allow you to try the system. If you have signed-up with FilesThruTheAir™ directly, you can upgrade to a Personal or Professional account at any time.

If this Cloud service has been provided to you by a 3rd party or your supplier, you should contact them directly about changing your account.

Click on the link below for further information on any on all of the FilesThruTheAir Cloud Options:

Is the FilesThruTheAir™ Cloud guaranteed to be “up” 24 hours a day, 365 days a year?

On rare occasions when the servers are upgraded or if any system maintenance is required, the FilesThruTheAir™ Cloud may have to be taken offline. This happens infrequently.  Notification to all Cloud users is given by email in advance of any offline time.

Why does the LCD on the sensor device show a different value to the reading on the FilesThruTheAir™ Cloud?

The LCD is updated every two seconds giving near-instantaneous readings at the sensor whereas the Cloud receives readings recorded at the sample rate and transmitted at the transmission rate.  In the case of the EL-WiFi-TH and EL-WiFi-TH+ sensors, the LCD will indicate measurements at 0.5°C and 1%RH resolution, but the FilesThruTheAir™ Cloud will always show a greater resolution. The FilesThruTheAir™ Cloud is where your raw data should be viewed for the highest resolution.

I noticed that you have a wide range of sensors. Can I add all the different device types to my FilesThruTheAir™ Cloud account?

Yes, all the various WiFi sensors we produce are designed to work with the FilesThruTheAir Cloud account.  However, the exception to this is the EL-WiFi-Alert device, which can only be installed locally on a PC and not in the Cloud. 

How many devices can I add to my FilesThruTheAir™ Cloud account?

It is feasible to have an unlimited number of sensors on your account, depending on your account type. To find out more about high capacity Cloud accounts, please contact FilesThruTheAir™ directly, or your supplier.

What if I forget my account password?

All passwords are held in an encrypted format on-line. If you forget a password, please use the “forgotten password” link on the Sign In screen. This will ask for your email address and will send you a link to reset your password.

Is there a way to reduce the number of email alerts I receive?

You can tailor the emails you receive in a few ways:

  1. When setting up email alerts in the Change Device Settings page, you can freely select which events cause emails to be sent. Perhaps you are only interested in the measured alarm levels and can un-tick some other options you don’t need.

  2. When you set-up an alarm level, you can delay the onset of the alarm by a selectable period of time. For example, when monitoring the temperature of a chiller, you might not need to know if the temperature exceeds the alarm level briefly (when someone opens and closes the door, for instance), but you do need to know if someone leaves the door open. When using dual channel sensor devices, alarm delay is independently settable for each channel.

  3. Have you set an alarm level that is too low or high? Every time a device goes into or out of alarm, an email is sent. If your device is constantly “chattering” around the alarm level, you will receive more emails.

  4. To reduce email traffic further, you can choose to reduce the number of alerts, by periodically summarising them into a single email. You can enable this option, and specify how often the summary emails are sent, in My Settings.

Why is a sensor alarm reset when I change an alarm setting?

Changing any alarm setting in Change Device Settings will cause the sensor to be refreshed with all alarm settings. This may cause an existing alarm condition to be reset.

Can I use sensor devices to monitor AC power?

Yes, you can receive email alerts when AC power fails or is restored. Simply connect the sensor device to a mains-derived power source (e.g. a USB +5V power supply), and enable email alerts for AC power in Change Device Settings.

Caution: Readings may be affected on some types of sensor device while the internal battery is being charged. However, once charged, continued connection of the charger or external battery pack will have no effect.


How does the FilesThruTheAir™ Cloud work with time-zones?

Free or Personal FilesThruTheAir™ Cloud accounts have a single time-zone which is specified at the time you sign up. All times and dates on the FilesThruTheAir™ Cloud will be shown for your selected time-zone.

In a Professional account, which accommodates multiple sites, you can specify a different time-zone for each location. When viewing data, event logs or device properties in a Professional account, times and dates are shown as local (i.e. at the sensor location).

What is a recording session?

In order to manage data received from your sensor device efficiently, the FilesThruTheAir™ Cloud divides data up into what we call ‘sessions’. Your sensor device will begin a session when it first begins logging. If you make any changes to the device such as a sample rate or alarm level change, the FilesThruTheAir™ Cloud closes and saves the current session and a new session is started. This is also the case when there is a time change due to Daylight Savings being applied automatically in Spring and Autumn. A complete list of all sessions is shown in the Other Sessions tab on the View Data page. All sessions are marked with a date and time to show the period that they cover, together with a device audit trail showing the changes which caused a new session to start. In a Professional account you can also export this device audit trail as a pdf.

Is there a limit to the maximum size of a session?

Sessions have been limited to a maximum of 300,000 readings to avoid problems associated with graphing very large data sets. This limit is equivalent to just over 1 month at the fastest sample rate (10 seconds). One year of logging can be achieved with sample rates of 2 minutes and above.

I have just gone into 'Adjust Device Settings' and there are some parameters highlighted red but the sensor does not show 'Setup Pending' on the devices screen. Why is this?

This is normally caused if you have exited the 'Adjust Device Settings' screen using the back button or closing the browser window. Go back into 'Adjust Device Settings' and either click Apply to keep the changes or Cancel to lose them.

What is an Audit Check?

In some applications it is necessary for a sensing device to be visited periodically and physically checked by the user. When enabled, the Audit Check function records these checks, which are displayed on the graph, and in tabular data. Change your Audit Check settings in the Change Device Settings page.

To record an Audit Check, the user simply presses and holds the device button for three seconds. On the LCD, both MIN and MAX flash together to acknowledge that the Audit Check has been recorded.

  • EL-WiFi Range 

The EL-WiFi loggers feature non-replaceable, rechargeable batteries. If you think the battery has gone flat, connect the logger to a PC using a Micro USB cable (CABLE USB A-MICRO B) for up to 24 hours.

Why do the LEDs flash after connecting my logger to a PC?

If the LEDs flash sequentially it may indicate that there is a problem with the battery. This could either be a flat battery, which should be replaced, or a battery where a passivation layer has formed. Leaving the data logger connected to a PC for about 30 seconds will remove this layer. After this, remove and re-install the batteries to reset the data logger. 

If you see the sequential LEDs after disconnecting the logger from a PC then the logging session will not start. You should check the battery condition and then repeat the setup procedure using the PC software.

What happens if I forget my login details for 21CFR USB software?

An administrator for the software will need to reset your password from the <Admin> <Edit User> menu. The next time you attempt to log in it will ask you to enter and confirm a new password.

How do I turn off the data logger?

It is not possible to turn off the data loggers. The GFX range of loggers has a 'stop' function on the logger but all other loggers require connecting to a PC to stop logging. Removing the battery will also stop the loggers. Any data on the logger will be stored on the device until it is downloaded using the PC software.

Do I need to reset my data logger every time I download the data to the PC?

Once you have downloaded the data off the data logger you will need to click the "set up and start USB data logger" button. This will take you through the set up process. The software will remember your previous settings to allow for a quick setup, or they can be changed for your new session.

How often should I send my data logger for recalibration?

We recommend recalibration on an annual basis, however your procedures may require something different to this. You can contact us for any information on the calibration services we can offer.

What is a Passivation layer?

If left unused for extended periods of time lithium metal batteries, including those used in the EasyLog range of data loggers, naturally form a non-conductive internal layer - a Passivation layer - preventing them from self-discharge and effectively increasing their shelf life. When first installed in the data logger, this may cause a momentary drop in the battery voltage (the Transient Minimum Voltage) as the internal layer is broken down, resulting in the data logger resetting. Inserting the batteries in the data logger and leaving it connected to a PC for about 30 seconds will remove this layer. After this, remove and re-install the batteries to reset the data logger. Overall battery life will not be affected.

Can I leave my data logger outside to measure the temperature and humidity?

Yes! Most of our data loggers have an IP rating that is suitable for use outdoors (you can check the datasheet if you are unsure about your particular model). If you are using the loggers in particularly harsh environments you may want to consider using the EL-USB-1-PRO, one of our Probe data loggers or the protective case EL-USB-CASE.

How long will the battery last in my data logger?

The battery life depends on the logger you have and the setting, on the data sheet for your product you can see the battery life shown in the specifications table.

Can an EL-USB-1-PRO be used in an autoclave with pressure?

One of the common uses of the EL-USB-1-PRO data logger is in autoclaves. An autoclave uses pressurised steam and high temperatures to kill bacteria etc (typically in laboratory and hospital environments). The maximum typical pressure for an autoclave is 30 bar. Testing in the Lascar environmental chamber has shown that the logger operates within specifications at 125°C (and will in fact continue working at higher temperatures, but not record a temperature higher than 125°C).

Lascar does not have the capability to test IP ratings beyond IP67. A long standing customer, Dynamic Load Monitoring (based in Southampton, UK) offered to assist in the testing of the EL-USB-1-PRO units using their hydraulic pressure testing equipment. This equipment is normally used to test underwater load cells, to pressures of 200 bar (equivalent to approximately 2000 meters depth in water).

The test setup consists of a metal cylinder with a capacity of approximately 20 litres, filled with oil slurry. Test samples are put into a nylon webbed sack, attached to a nylon rope and lowered into the oil slurry. A cap is bolted into place using up to 8 large bolts. Pressure is adjusted using a hand operated hydraulic pump. The internal pressure is read back from an analogue gauge, located on the hand pump.  When a sample is removed, it is cleaned with a light petroleum based fluid.  Three sets of EL-USB-1-PRO metalwork were taken from stock for the tests. No internal parts were included, as any pressure changes are unlikely to affect operation. Each logger was fitted with two Viton o-rings (Viton is compatible with petroleum based substances) and lubricated with silicon grease. The metalwork was assembled by hand, as per a typical user.

Testing was performed on the 17th November 2009.

Test 1: 30 bar for 15 minutes. Passed.
Test 2: 50 bar for 30 minutes. Passed.

After each test, both seals on all three loggers were checked for ingress. No oil was present (The oil would be easy to see, as it is a black). Further tests may be carried out in future, to find the failure pressure. At present however, 50 bar far exceeds the requirements of the typical user.

Based on the above, Lascar could quote pressures of up to 45 bar on the datasheet. This does however assume that the correct o-rings are used, and that they are in good condition.

Can an EL-USB-3 read negative voltage?

No.  In the custom calibration you can turn it into real things 0v = -30 degrees C and 30v = 200 degrees C.  Voltages mean something else.

Can an EL-USB-5 be set up to “volt free" mode?

Yes, the unit does have volt free contacts as an option.  In volt free contacts the logger supplies approx 30uA @ 3.3V. When contacts are open the input is high (ONE), when contacts are closed the input is low (ZERO), this displays negative logic.

Volt-free contact operation: assuming a normally open switch, events will be generated as follows depending on the edge mode that has been selected.

  • Rising Edge = Closed going open
  • Falling Edge = Open going closed


Are Lascar’s data loggers waterproof?

All of our data loggers have an IP rating on their datasheet. The IP rating is a two digit code indicating the level of protection that is provided against solid objects and ingress of water as detailed below:

First Digit - Mechanical Protection

  1. Protected against solid objects over 50mm
  2. Protected against solid objects over 12mm
  3. Protected against solid objects over 2.5mm
  4. Protected against solid objects over 1mm
  5. Protected against harmful dust, limited ingress permitted
  6. Totally protected against dust


Second Digit - Water Ingress Protection

  1. Protected against vertically falling drops of water
  2. Protected against direct sprays of water up to 15° from the vertical
  3. Protected against direct sprays of water up to 60° from the vertical
  4. Protected against water splashed from all directions, limited ingress permitted
  5. Protected against low pressure jets of water from all directions, limited ingress permitted
  6. Protected against strong jets of water, limited ingress permitted
  7. Protected against immersion up to 1m depth for up to 30 minutes

Which type of battery should I use with your data loggers?

The battery we use for our loggers are:

  • EL-GFX

For these products you need 2 x BAT 3V6 1/2AA.

  • EL-USB

For most USB loggers you need 1 x BAT 3V6 1/2AA.  The loggers that need a different battery are below


You will need 1 x BAT 3VX5.  They come in a pack of 5.

  • EL-USB-1-PRO

You will need 1 x BAT 3V6 2/3AA H TEMP.

  • EL-USB-1-RCG

The EL-USB-1-RCG features a non-replaceable, rechargeable battery. If you think the battery has gone flat, connect the logger to a PC using a Mini USB cable (CABLE USB A-MF) for up to five hours.


This product uses two standard AA batteries.

  • EL-WiFi Range 

The EL-WiFi loggers feature non-replaceable, rechargeable batteries. If you think the battery has gone flat, connect the logger to a PC using a Micro USB cable (CABLE USB A-MICRO B) for up to 24 hours.

Which data loggers are compatible with the EL-Datapad?

The following data loggers work with the EL-Datapad:

  • EL-USB-1
  • EL-USB-1-LCD
  • EL-USB-1-PRO
  • EL-USB-2
  • EL-USB-2+
  • EL-USB-2-LCD
  • EL-USB-2-LCD+

What does '---' mean on my LCD data logger?

If you see '---' on the display of your data logger when you press the button, this indicates that the logger is not logging.

What does 'PS' mean on my LCD data logger?

'PS' indicates that the data logger is in Push-to-Start mode. Pressing the button will start the data logging session.

What does 'dS' mean on my LCD data logger?

'dS' indicates that the data logger is in Delayed Start mode. The data logging session will start at the time specified when the logger was set up.

Can the EasyLog software compatible with MAC, Linux or Unix?

Unfortunately we do not have Easylog sensor software that is compatible with Mac, Linux or Unix as there are no available drivers for the main sensor and control device that is used in our loggers, other than Windows drivers.  As the demand for alternative drivers is very low, the device manufacturer is unlikely to invest in the cost of developing and supporting alternative drivers.

One possible solution for Mac would be to install the software on a under a Windows emulator. Customers are using Parallels or VMware Fusion. The EL-USB-WIN software can be downloaded from here.  Whilst, we cannot guarantee the smooth operation of our software using this method, many customers report satisfactory use.

Mac users should under no circumstance, attempt to install the EL-USB-WIN software from the software disc previously supplied with the logger, as the small diameter of the disk could cause significant damage to the Mac disc drive. 

The only other solution that we can offer for temperature or temperature and humidity loggers, only, is to use the EL-DataPad to set up and manage the loggers.  This will allow you to download the data from the logger which is converted into a comma separated .txt file in the EL-DataPad.  If you then plug the EL-DataPad into a USB port in the alternative platform, it will normally be seen as a mass storage device.  You can then transfer the comma separated.txt file into your platform and manipulate this in a spread sheet program.

Can the data loggers record in real time?

The only data logger we have which records in real time is the EL-USB-RT.

How many data loggers can I set up on a PC?

You can set up as many EL-USB and EL-GFX data loggers as you like on a PC, but you can only connect one logger at a time.

Will the device work with a VPN (Virtual Private Network)?

Due to the increased latency introduced by establishing a connection that can cause time-out problems, we advise against it, but provided that the VPN can allow the sensor device internet access via TCP port 14354, it is technically possible.

How do I update the firmware on my EL-DataPad?

  1. Turn your EL-DataPad on and connect it to a USB port on your PC.
  2. Download the latest EL-DataPad firmware and unzip the file. Simply double click the zip file to open it.
  3. Drag and drop, extract or copy the file in the zip to your EL-DataPad.
  4. Turn the EL-DataPad on again by pushing the button. The unit will restart and automatically load the update file.

The firmware is updated. To check the firmware version on the EL-DataPad press the SETTINGS icon on the bottom right of your screen and select the STATUS button.


Is the SGD 24/28/35-M waterproof?

Unfortunately not. Due to the nature of the display and touch screen, we would advise against using the display in a wet or overly humid environment. Instead, we would suggest using the SGD 24-M-IP as this offers a full IP67 rating.

Where can I find new meter configurations or upgrade to the latest version of software?

On the ‘Choose Meter Style’ page within the PanelPilot M software, there is a ‘Check for updates’ button. If you click on this button, the software will start to search for the latest meter configuration and software updates and notify you if there are new additions to download.

Can I add my company logo to the display?

Yes. When configuring your meter using the PanelPilot M software, the last set up stage will ask you whether or not you would like to add a company logo to the display. If you chose to do this, the company logo will be present on the display for the first few seconds when the display is powered up.

Can I dim the brightness on my PanelPilot?

Yes. Using the PanelPilot M software, there is an option at the end of the configuration stage to select the display brightness. Please note that once set, there is not currently a way to adjust the display brightness without reconfiguring your display.

I see that you have a temperature add on board for the PanelPilot M. Can I data log with this?

Unfortunately not. While we do have a configuration that will give you the live reading of the temperature (using the thermocouple add on board) the display does not support data logging. We would recommend using the EL-SGD 43-ATP instead.

I am looking for a configuration that is not listed in the PanelPilot software. Can you make one for me?

Certainly! Using our PanelPilot Custom Design service, we can make bespoke configurations that are tailored to your requirements. Please contact our sales team to find out more.

My graphics aren’t appearing in exactly the same place on the display as they are on the emulator. Why is this happening?

Unfortunately the rendering engines used on the emulator and on the embedded display are not exactly the same.  This can lead to very minor differences in the positions of graphics. Normally this is not noticeable but it can sometimes mean that the rotation of a needle, for example, is slightly off.

Could you explain what 21 CFR Part 11 is?

The US FDA (Food & Drugs Administration) Code of Federal Regulations 21 Part 11, is an extension to the existing regulations that defines which electronic records and signatures that are to be considered accurate to replace paper records for the Pharmaceutical and Medical industry.  Our system has been designed to assist companies comply with these regulations.
