* DCV <1000dgt, add 6 dgt to the accuracy. ACV <1000dgt, add 3 dgt to the
accuracy.
Overload protection: 1000Vrms
Input Impedance: 3.5Me // <100pF
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 nonsine wave below half scale. For non-sine
wave (50/60Hz) add the following Crest Factor corrections:
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.
