Purpose ................. to measure on pulse width modulated
signals, like motor drive inverter outputs
Principle ......... readings show the effective voltage based
on the average value of samples over a
whole number of periods of the fundamental
frequency
Accuracy ............................ as Vrms for sinewave signals
