You can measure starting (inrush) current , running current, and current imbal-
ance in AC Motor circuits. Inrush current is typically 6-8 times the value of run-
ning current, depending on the motor type..
1. St the rotary switch to "A".
2. Press and hold the PEAK button(>1sec) to enter 1ms PEAK hold mode.
3. Clamp around a motor phase conductor. Be Sure the clamp jaws are com
