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 300 mA, decreasing linearly to crest factor ≤1.5 at 600 mA. For non-sinusoidal waveforms add +(2% reading + 2% FS)
typical, for a crest factor up to 3.
