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
