AC Conversion Type: * add 2 digits to accuracy when reading less
15% of full scale.
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 add the following
Crest Factor corrections:
For Crest Factor of 1.4 to 2.0, add 1.0% to accuracy.
