AC conversion type
AC Conversions are ac-coupled, true RMS
responding, calibrated to the RMS value
of a sine wave input. Accuracies are
given for sine wave at full scale and non-
sine wave below half scale. For non-sine
wave (50/60 Hz) add the following Crest
Factor corrections:
Crest factor 1.4 to 2.0
2.0 to 2.5
2.5 to 3.0
