True RMS ACV & ACA clamp-on accuracies are specified from 0% to 100% of range or
otherwise specified. Maximum Crest Factor are as specified below, and with frequency
spectrums, besides fundamentals, fall within the meter specified AC bandwidth for non-
sinusoidal waveforms. Fundamentals are specified at 50Hz and 60Hz.
