Summary: 
Directions on calculating average and peaktopeak voltages/current values based on waveform snapshots using formulas. 
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.

Zerotopeak voltages and currents are calculated on the samples taken during each 0.02 second snapshot by the following formula:
max(x)  min(x)

The longerterm 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:
NewAverage
=
( PreviousSampleCount x PreviousAverage ) + SnapshotAverage ___________________________________________________________
PreviousSampleCount + 1
