EL-WEM Quick Start Guide
Wireless Indoor Air Quality Monitor
Your data, anytime, anywhere
The EL-WEM simultaneously measures
a number of different parameters that
affect air quality and uses them to
calculate an overall Indoor Air
Quality (IAQ) level.
The colour of the status ring shows the
current IAQ level. If the IAQ is Poor or
Inadequate the status ring will turn red
and the sounder, if activated, will beep
to alert those nearby. If you have
configured email or SMS notifications
on the Cloud these will automatically
be sent to your selected recipients.

Calibration Mode
(EL-WEM+ only)

The carbon dioxide (CO
2
) sensor in the
EL-WEM+ is extremely accurate and to
maintain this accuracy it should be
calibrated every 6 months.
First, provide as much fresh air as
possible to the EL-WEM+, for example
place it next to an open window. Then
press and hold the power button for 10
seconds; the sounder will beep and the
status ring will turn white.
The calibration process is automatic
and will take a little while; when it’s
complete the sounder will beep again
and the EL-WEM+ will return to its
normal monitoring mode. If for any
reason calibration fails to complete the
sounder will beep
4 times at the end
of the process.
You should then
ensure the supply
of fresh air is
adequate and
restart calibration
mode.

The EL-WEM contains a back-up battery
that can power the unit if mains power
is lost. When running from the battery
the EL-WEM goes into low power mode,
and will upload data to the Cloud once an
hour, although notifications for poor indoor
air quality will be sent immediately. It is
not possible to enter configuration mode
or calibration mode until mains power is
restored.
When your WEM is in Low Power Mode
you may get ‘Connection Lost’ notifications
from the Cloud (if you have set them up) as
in Low Power Mode it doesn’t connect to
the Cloud as frequently as normal.
The battery is intended as an emergency
backup only and should not be used to
power your EL-WEM for long periods.
The battery cannot be accessed or changed
by the user and is recharged automatically
when mains power is restored.

There are five levels
Your WEM contains an alarm sounder that
you can activate from the EasyLog Cloud, to
give an audible warning if the IAQ level is
Poor or Inadequate. There is also an option
to set a time period each day when the
status ring and sounder are turned off.

Connect to the Cloud
4
Log in to the EasyLog Cloud App on your mobile device.
Select ‘Setup Device’ and
follow the on-screen instructions to
configure your EL-WEM. When setup is complete the sounder
will beep and the EL-WEM will automatically start monitoring your
indoor air quality.
When connected to the EasyLog Cloud, your EL-WEM will regularly upload
data from all the air quality parameters it measures. You can then graph,
analyse and share this data and also set automatic notifications via email
or SMS to keep you informed at all times.
If you choose not to connect your EL-WEM to the Cloud it will still monitor indoor air
quality levels, but it will not record data and you won’t be able to use of any of the additional
features of the EasyLog Cloud.

After you’ve connected the EL-WEM to your WiFi network, if the power button starts flashing again it means the monitor has been
unable to connect to the network to upload data. The EL-WEM will automatically try to reconnect, but you should also check if your
WiFi network is available. If you want to perform an immediate upload to the Cloud and your network is available, do a short press of
the power button. This will create an audit mark in the event record. To reconfigure the WiFi settings (e.g. to change your EL-WEM to
use a different WiFi network), press the Setup button on the base of the unit for 3 seconds. This restarts the setup process explained
in section 4 above.
