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.
Posion Error of Clamp: ±1.5% of LCD reading.
Range Resoluon Accuracy
60.00 A(1) 0.01 A ± (1.5% + 10d)(2)
300.0 A 0.1 A ± (1.5% + 5d)
DC Current
Range Resoluon Accuracy(50~100Hz) Accuracy(100~400Hz)
60.00 A 0.01 A ± (1.5% + 25d) ± (2.5% + 25d)
300.0 A 0.1 A ± (1.5% + 5d) ± (2.5% + 5d)
AC Current
(1) There are less than 0.3A variaon as measuring in dierent direcons.
(2) Add 10D to accuracy in Auto AC & DC Sense Mode.
Frequency Response: 50~400Hz (Sine Wave).
