Electrical Specifications
Accuracy is given as ±(% of r counts of least
significant digit) at
23°C ± 5°C (≤ 80% R.H.)
AC Function
• ACA specifications are ac coupled, true RMS.
• For non-sinusoidal waveforms, Additional
Accuracy by Crest Factor (C.F.):
Add 1.0% for C.F. 1.0 to 2.0
Add 2.5% for C.F. 2.0 to 2.5
Add 4.0% for C.F. 2.5 to 3.0
• Max. Crest Factor of Input Signal:
3.0 @ 3000 counts
2.0 @ 4500 counts
1.5 @ 6000 counts
• Frequency Response is specified for sine
waveform.

*
Minimum Reading is 10uA
**
Frequency response is 15 to 50 Hz.
When frequency < 30 Hz, add 3.0% to
accuracy.
***
Frequency response is 60 to 10k Hz.
When frequency > 1k Hz, add 0.5% to
accuracy.
Minimum Resolution :
1uA
Position Error : ±1% of reading
Overload Protection : 60A
