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., AC A specifications are ac coupled, true
R.M.S. The crest factor may be up to 3.0 as 4000 counts.
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
Position Error of Clamp: ±1.5% of display reading

2)
± (1.5 % + 5 LSD)
1)
There are less than 0.3A variations as measuring in
different directions.
2)
Add 10 LSD to accuracy in Auto AC / DC A mode.
