If the GPS can’t send reliable time information to the meter (it loses contact with satellites, for
instance) the meter will wait for 1 hour before starting to accept time setting from other sources, like
PQ Schedule. You can study the
RTC Sync
event in the event list and see if the meter has been
synchronized by the GPS or by PQ Schedule.
Figure 44 - RTC sync information event
The last digit indicates the source of time synchronization. “0” means PQ Schedule or manually by
PQ Online. “1” means by GPS.
If there is a communication error between the GPS and the meter there are several protective
mechanisms in the software that prevent incorrect time from setting the meter. Each time, for
instance, is verified twice before setting.
When the clock is set in the meter and the deviation is greater than 1 minute, an event will be
generated (
clock deviation
). This event could also be connected to a visual and/or email alarm.
The Clock Sync event, that can also be seen in the event list, only informs you that PQ Schedule has
tried to synchronize.

GPS Connection instruction for UP2210/UP2210R
This chapter describes the connection procedure for connecting a Garmin GPS16x-LVS to one or
more UP2210 or a UP2210R measurement instruments.
To perform this installation, you will need:
A Garmin GPS16x-LVS antenna. Unipower article no: 22-4042.
A UP2210 or UP2210R with the 22-4052 module installed.
4 wire signal/connection cable (for several UP2210/UP2210R to the same GPS)
The appropriate tools (Flat head screwdriver, cable stripper tool etc.)
Optionally if you are going to cascade several UP2210/UP2210R meters to the same GPS
you will need additional connection cable.
1.
Look at the RJ45 connector at the end of the cable connected to the GPS and identify in
which order the cables inside is connected from left to right.
In this case
the cables are in the
following order:
1
Red
2
Black
3
Yellow
