are the instantaneous voltage and current values.
n is the number of samples.
I
I
is the measured current for each data update interval.
N is the number of data updates.
In power integration and, when the measurement mode is set to DC, current integration, the
instantaneous power or current values are integrated. When the measurement mode has been set to
RMS,thecurrentvaluesmeasuredateachdataupdateinterval(seesection2.10)areintegrated.
Note
If you stop integration, the integration process stops at the integrated value and elapsed integration time of
the previous display update. The measured values between the previous display update and the execution of
the integration stop are not integrated.
Display Resolution during Integration
The display resolution of integrated values is normally 99999 counts. The display resolution can go up
to 999999 counts when the unit is MWh or MAh.
When the integrated value becomes large and reaches 100000 counts, the decimal point is
automatically moved. For example, when 0.0001 mWh is added to 9.9999 mWh, the display switches
to 10.000 mWh.
