AC Voltage Specifications
AC Voltage specifications are for ac sinewave signals >5 % of range. For inputs from 1 % to 5 % of range and <50 kHz,
add an additional error of 0.1 % of range, and for 50kHz to 100 kHz, add 0.13 % of range.
Maximum Input ................................................. 750 V rms or 1000 V peak or 8 x 10
7
Volts-Hertz product
Measurement Method ....................................... AC-coupled true-rms. Measures the ac component of input with up to
1000 V dc bias on any range.
AC Filter Bandwidth:
Slow ............................................................... 20 Hz – 100 kHz
Common Mode Rejection................................. 60 dB at 50 Hz or 60 Hz (1 kΩ unbalance)
Maximum Crest Factor .................................... 3:1 at Full Scale
Additional Crest Factor Errors (<100 Hz) ...... Crest Factor 1-2, 0.05 % of full scale
Crest Factor 2-3, 0.2 % of full scale
