Incremental energy

Incremental energy allows you to define a start time, end time, and the time interval (increments)
for incremental energy accumulation.
At the end of each interval, the energy accumulated during that period is stored. By default, the
meter only records the previous interval's incremental energy and the instantaneous energy
accumulations in the active interval.
The first interval of incremental energy accumulation begins at the specified start time.
Incremental energy ends at the specified end time, which may result in a truncated interval if the
interval duration does not divide evenly into the overall incremental energy duration. For example,
an interval duration of three hours with an overall duration of five hours truncates the last interval
duration to two hours. The latest value for the specified end time is midnight (24:00).
Your start time must be before the end time and after midnight, and the period over which
incremental energy is accumulated cannot include midnight. This is because your meter's start
and end times are defined relative to midnight.
Start: 6AM, End:
12AM, interval: 3 hrs
Start: 6AM, End:
2AM, interval: 3 hrs
253
Incremental energy accumulates from 6AM to midnight in intervals of
3 hours.
Incremental energy will not function. End time must be after start
time and before or equal to midnight.
