1 kHz bandwidth
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.
