Electrical Specifications
Accuracy is ±(% reading + number of digits) at 23°C ± 5°C < 80%RH.
(1) Voltage
ACD-50NAV, ACD-51NAV, ACDC-52NAV, ACD-53NAV, ACDC-54NAV
Function Range Accuracy*
DC V
99.99V
± (0.7% + 2dgt)
999.9V
AC V
99.99V ± (1.0% + 5dgt)
50 ~ 500Hz 999.9V
LPF
99.99V 50 ~ 60Hz ± (1% + 5dgt)
61 ~ 400Hz ± (5% + 5dgt) 999.9V
* 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.
CF 3 @ 460V,460A (for ACD-53NAV, ACDC-54NAV),
280A (for ACD-50NAV, ACD-51NAV, ACDC-52NAV)
2 @ 690V, 690A (for ACD-53NAV, ACDC-54NAV),
420A (for ACD-50NAV, ACD-51NAV, ACDC-52NAV)
AC+DC Vrms Accuracy: same as ACV spec. +DCV spec.
