Confirming GSM Communications
After installing the meter, it can take up to 5 minutes for the meter to find a GSM network. Press the 'Display
Cycle' button to show the GSM signal quality. If the display shows signal less than 14 you will need to install an
external antenna to improve the signal. The external antenna connects to the SMA socket on the side of the
unit. Recheck the GSM signal after installing the signal booster.

If the signal is still below 14 the location may not be suitable for the installation of this meter.
Once you have established that there is sufficient GSM signal quality, complete the system installation.
After installation the LED lights on the top half of the meter on the communications module with flash in the
following manner.

Troubleshooting communication issues
with the Emlite meter
The internal roaming SIM requires a CSQ signal
strength of 14 or more. The is important because
even though the meter may communicate at lower
readings the service will be intermittent and
unreliable. The signal strength should be checked
in close proximity to the intended position of the
antenna. If possible take the antenna you intend to
use and measure with that antenna to your GSM
signal analyser. The position is important because
the signal can vary dramatically over less than a few
1.
No matter how strong the signal may be the unit
will still not connect if there is interference from
other nearby RF equipment. Check that the
intended site for installation is not close to sources
of RF interference such as radio transmitters, high
current conductors, electric motors, inverters or

The meter will auto-register with the OpenMetrics web portal.
It can take up to 10 minutes for the meter to reach GPRS state.
GSM Signal Analyser
The
OpenMetrics
® Web Portal will update the latest meter readings
on the day after meter installation.
