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.
