Crest Factor Table
Background
Crest factor is the ratio of the peak signal amplitude to the
RMS value of the signal. It determines the accuracy of AC
measurement. If the crest factor is less than 3.0, voltage
measurement will not result in error due to dynamic range
limitations at full scale. If the crest factor is more than 3.0,
it usually indicates an abnormal waveform as seen from the
below table.
