AC Conversion.................................................... Inputs are ac-coupled and calibrated to the rms value of sine wave
input. Conversions are true-rms responding and specified from 5
% to 100 % of range. Input signal crest factor can be up to 3 at up
to 500 V, decreasing linearly to crest factor <= 1.5 at 1000 V. For
non-sinusoidal waveforms add
±
(2 % r 2 % FS) typical,
for a crest factor up to 3.
