Crest Factor Error

Non-sinusoidal input signals with crest factors between 2 and 3 and pulse widths 100 µs and longer add 0.2% to the accuracy specifications.

Common Mode Rejection

80 dB minimum at 50 or 60 Hz ± 0.1%, 1 kΩ imbalance, slow rate

Maximum AC Input

300V rms or 424V peak on channels 0, 1, and 11

150V rms or 212V peak on channels 2 to 10 and 12 to 20 Voltage ratings between channels must not be exceeded

2 x 106 Volt-Hertz product on any range, normal mode input

1 x 10 6 Volt-Hertz product on any range, common mode input

DC Component Error

SCAN and first MONitor measurements will be incorrect if the dc signal component exceeds 60 counts in slow rate or 10 counts in fast rate. To measure ac with a dc component present, MONitor the input and wait 5 seconds before recording the measurement.
