VFC 600.0mA~60A 0.1mA~0.01A ±(4.0% + 10d) 100A / 600VAC
Notes: Accuracy stated for 5~100% of range; <20 digit residual reading for 600mA open circuit.
AC Crest Factor may reach 3.0 at 4000 counts; for non ‐ sinusoidal waveforms the Crest Factor error
increases per the following: Add 3% when the crest factor is 1~2; Add 5% when the crest factor is 2~2.5;
Add 7% when the crest factor is 2.5~3
