Average voltages and currents are calculated on the samples taken during each snapshot as the sum of (x)/N, where x is the array of samples acquired, and N is the number of samples.
-
Zero-to-peak voltages and currents are calculated on the samples taken during each 0.02 second period by the following formula:
-
The longer-term averages are calculated by accumulating averages for the specified period. They are then reset in preparation for the next calculation. The formula used is as follows:
