AC Function 
ACA specifications are ac coupled, true R.M.S. 
For non-sinusoidal waveforms, Additional 
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. 
Electrical Specifications 
 
Accuracy is given as ±(% of reading + counts of 
least significant digit) at 23°C ± 5°C, with 
relative humidity Less than 80% R.H. 
Accuracy is specified for a period of one year 
after calibration. 
 
Position Error of Clamp : 
Accuracy and position error assumes central-
ized primary conductor at optimum position, no 
external electrical or magnetic field, and within 
operating temperature range.
