True RMS accuracy of ACV is specified from 5% to 100% of range, &
ACA is specified from 10% to 100% of range, or otherwise specified.
Maximum Crest Factor <1.75 : 1 at full scale & <3.5 : 1 at half scale,
and with frequency spectrums, besides fundamentals, fall within the
meter specified AC bandwidth for non-sinusoidal waveforms.
