Overload ............................................................. 600 mA for 2 minutes maximum
Fuse Protection for mA Input .............................. 0.44 mA, 1000 V, IR 10 kA
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.
