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||Incremental energy accumulates from 6AM to midnight in intervals of 3 hours.|
|Start: 6AM, End: 2AM, interval: 3 hrs||Incremental energy will not function. End time must be after start time and before or equal to midnight.|
Incremental energy helps provide information for analyzing energy and power usage against present or future utility rates, and is useful for measuring energy consumption by shift or for a specific process.
When configuring incremental energy, shorter incremental energy periods provide more granular data which can make the data easier to use for comparison purposes.
Incremental energy example
Start time: 8AM or 08:00
End time: 12AM or 24:00
Interval: 420 minutes (7 hours)
