WATCHDOG ACTIVITY
NON VOLATILE MEMORY NON
FATAL ERROR
When these non-fatal alarms are detected, the meter uses the
previous 4 hours backup values.
It is recommended you remove/replace the meter, or at least erase
the fault with the support software and investigate the situation.

EXTERNAL CLOCK
INCOHERENCE
A non-fatal alarm, where the RTC chip does not accept external
programming. If it occurs only once, it has little effect on the meters
time management.
