Support - EL-WEM Air Quality Monitors
The air quality sensors in the EL-WEM are very sensitive, and take approximately 5 minutes to self-calibrate when the device is turned on. After this period of time the EL-WEM will automatically start logging your readings.
EL-WIFI - When the sensor is displaying the main reading screen on the LCD, press the button on the front three 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.
EL-IOT - You must hold the main button on the device for 1-8 Seconds. This acknowledges an alarm, creates an audit event in the record, and forces data synchronisation with the Cloud.
EL-WEM - As the EL-WEM has a fast update rate by default, there is no way to force transmission with the cloud.
IT IS RECOMMENDED THAT YOU ARCHIVE THE DEVICE ON YOUR EASYLOG CLOUD DEVICES PAGE BEFORE UNDERTAKING A FACTORY RESET.
EL-WIFI - The device can be reset by holding the button for 10 seconds. Release the button when RST appears on the screen. The device will retain all settings but will lose any data that had not been transferred to the EasyLog Cloud. It will continue to be connected to the account it was set up with and will simply start a new recording session.
If necessary, a full factory reset can also be performed by holding the button for 20 seconds until FArS appears on the screen. Doing this will return the device to the factory state, deleting all settings and clearing any remaining data. The device will no longer be connected to any network or EasyLog Cloud account.
EL-IOT – To reset the device, you must remove the battery cover with a screwdriver. Once removed, there is a reset button that can be pressed using a pin. Hold this button for a few seconds until the device beeps.
EL-WEM – To soft reset the device, there is a reset button on the bottom of the base. Press the button and release after 1 second.
To factory reset the device, hold the same reset button for 5 seconds.
There are several factors which can significantly affect the battery life of the device including; Sync Schedule, Wi-Fi encryption method, Wi-Fi encryption key rotation frequency (determined by the Access Point or router), signal strength between access point or router and device, presence volume and type of Wi-Fi traffic from other devices, sample rate, and operating temperature. In our tests, we regularly achieve battery life in excess of six months with a transmission rate of one hour or more at ambient temperatures. The device will not take readings when there is no power, but all readings taken prior to the loss of power will be synchronised. Once recharged, the device will reconnect to the EasyLog Cloud, start a new recording session, and continue recording.
EL-WIFI – The battery in this device is rechargeable with the charge typically lasting 6 months. You can also power the device through a mains power supply.
EL-IOT – The batteries will typically last more than one year. The device takes 4 x AA 1.5V batteries
EL-WEM – This device must be always powered by a mains power supply.
