Notes:
Accuracy is given as ± (% of reading + least significant counts) at 23C ±5C with relative humidity
lower than 80%. Accuracy is specified for a period of one year after calibration.
Position Error of Clamp: Accuracy and position error assumes centralized primary conductor at
optimum position, no external electrical or magnetic field, and within operating temperature
range.
Distance from
optimum position
*Add this error to the AC Current accuracy specification listed earlier in this section.
LCD displays '0' counts when the reading is < 10 counts.
ACA specifications are AC Coupled, True RMS.
For non‐sinusoidal waveforms, additional accuracy Crest Factor (C.F.) considerations exist as
detailed below:
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
