Extech Instruments MA61 User Manual page 17

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
