PQ Schedule. You can study the RTC Sync event in the event list and see if the meter has been
synched by the GPS or by PQSchedule (see Figure 48).
Figure 48 RTC sync information event
The last digit indicates the source of time synchronisation. “0” means PQSchedule or manually by
PQ Online. “1” means by GPS.
If there is a communications error between the GPS and the meter there are several protective
mechanisms in the software that prevents incorrect time from setting the meter. Each time, for
instance, is verified twice before setting the time.
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
made an attempt to synchronise the clock in the meter. The RTC Sync event tells you what really
happened.
