AC Conversion Inputs are ac coupled true-rms responding and specified from 5 % to 100 % of range. Input
signal crest factor can be up to 3 up to 500 V, decreasing linearly to a crest factor ≤1.5 at
1000 V. For non-sinusoidal waveforms add ± (2 % reading + 2 % FS) typical, for a crest factor
up to 3.
