Quality Information
The two following quality bits are stored for each counter in separate holding registers:
•
Overflow OV: The internal counter pulse exceeds 31 bits. The Overflow bit is reset once the counter has
been reset.
•
Invalid IV: The counter value is invalid due to a reset/device start. The bit is deleted 1 min after the device
start.

Energy per Counter Pulse
The energy per counter pulse is identical for all energy metered values calculated from the measured AC quan-
tities so that only one value is transmitted for all energy counters. The energy per counter pulse is determined
by the AC network configuration.
At the rated value 60 000 counter pulses per hour are recorded for V
A counter overflow occurs about 4 years after the counters were reset when V
continuously.
