Electrical Specications
Accuracy is given as ±(% reading + number of digits) at 23°C ± 5°C < 80%RH. Accuracy is
specied for a period of one year aer calibraon.
AC Funcon
ACV and ACA specicaons are ac coupled, true R.M.S.
The crest factor may be up to 3.0 as 4000 counts.
For non-sinusoidal waveforms, Addional Accuracy
by Crest Factor (C.F.):
Add 3.0% for C.F. 1.0 ~ 2.0.
Add 5.0% for C.F. 2.0 ~ 2.5.
Add 7.0% for C.F. 2.5 ~ 3.0.
Range Resoluon Accuracy
2.1 V ~ 1000 V 0.1 V ± (0.3% + 2d)
-0.7 V ~ 1000 V 0.1 V ± (0.3% + 2d)
DC Voltage
Range Resoluon Accuracy
1.3V~1000V 0.1 V ± (0.9% + 3d)
(50Hz~60Hz)
± (1.5% + 3d)
(61Hz~500Hz)
AC Voltage
Input Impedance: > 6kΩ for input voltage up to 30V. Impedance increases to approximate
420kΩ at 1000V.
Overload Protecon: AC 1000Vrms, 1000Vdc
Maximum Operaon Time: 30sec.for more than 30V.
