AC Conversion Type: AC conversions are ac-coupled, true rms responding,
Calibrated to the sine wave input.
For non-sine wave add the following Crest Factor conditions:
For Crest Factor of 1.4 to 2.0, add 1.0% to accuracy.
For Crest Factor of 2.0 to 2.5, add 2.5% to accuracy.
For Crest Factor of 2.5 to 3.0, add 4.0% to accuracy.
AC + DC Accuracy: Add 1.0% to accuracy.
HFR Accuracy: Add 1.0% to accuracy at 40Hz ~ 400Hz
