FEATURES

Average sensing RMS calibrated
RMS (Root-Mean-Square) is the term used to describe the effective or equivalent
DC value of an AC signal. Most digital multimeters use average sensing RMS
calibrated technique to measure RMS values of AC signals. This technique is to
obtain the average value by rectifying and filtering the AC signal. The average
value is then scaled upward (calibrated) to read the RMS value of a sine wave. In
measuring pure sinusoidal waveform, this technique is fast, accurate, and cost
effective. In measuring non-sinusoidal waveforms, however, significant errors
can be introduced because of different scaling factors relating average to RMS
values.
