Permanent checksum error in internal RAM
Permanent checksum error in external RAM
INTERNAL PROGRAM MEMORY ERROR
Permanent checksum error in internal code
EXTERNAL PROGRAM MEMORY ERROR
Permanent checksum error in external code
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.
