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.
