Inrush Current Measurement (AC INRUSH)

The instrument can measure AC inrush current.

1Turn off the power to the object under measurement.

2Press RANGE to set the range.

3Press and hold the MAX/MIN key and RANGE key simultaneously for 1 s or more to enable inrush current measurement.

The instrument cannot measure inrush current including DC components accurately.

4Clamp the wire.

5Turn on the power to the object under measurement.

If inrush current occurs, the measured value will be held.

The inrush measurement range is set as follows depending on the range when the current is measured.

Range when the current is measured	Inrush measurement range	Trigger threshold value (PEAK value)
60.00 mA 600.0 mA	600.0 mA range	Greater than or equal to +60.0 mA or less than or equal to −60.0 mA
6.000 A	6.000 A range	Greater than or equal to +0.600 A or less than or equal to −0.600 A
60.00 A	60.00 A range	Greater than or equal to +2.00 A or less than or equal to −2.00 A
600.0 A Auto	600.0 A range	Greater than or equal to +20.0 A or less than or equal to −20.0 A

(To return to current measurement, hold down the MAX/MIN and RANGE keys simultaneously for 1 s or more.)
