AC Current

The following ac current specifications are for sinusoidal signals with amplitudes greater than 5 % of range. For inputs
from 1 % to 5 % of range, add an additional error of 0.1 % of range.
Input Protection ................................................ Tool accessible 11 A / 1000 V and 440 mA / 1000 V fuses
Measurement Method ....................................... AC-coupled True RMS
Shunt Resistance.............................................. 0.01
AC Filter Bandwidth ......................................... 20 Hz – 100 kHz
Maximum Crest Factor ..................................... 3:1 at Full Scale
Additional Crest Factor Errors (<100 Hz) ...... Crest Factor 1-2, 0.05 % of full scale
