Overload ............................................................600 mA for 2 minutes maximum
Overload Protection ............................................ 440 mA, 1000 V, FAST fuse
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 full scale 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.
