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 up to 500 V, decreasing linearly to crest factor <= 1.5 at 1000 V. For
non-sinusoidal waveforms add
±
(2 % reading + 2 % FS) typical, for a crest factor up to 3.
