Amps AC (AAC), Frequency (Hz) through the clamp and Inrush AAC
current is measured in the VAC/AAC/Hz switch position shown above.
Inrush AAC Current
Inrush mode captures the starting amp draw of a motor. Starting amp
draw can assist in diagnosing a motor before it fails.
Activate Inrush mode
1 Rotate selector switch to VAC/AAC/Hz.
2 Press SELECT once to show AAC on upper display. Press INRUSH on the
right side of meter to activate.
3 Clamp meter around the motor’s start wire. Turn motor on. The
starting amp draw will hold on the upper display.
4 Press INRUSH to reset the test. Press INRUSH for 2 seconds to exit
Inrush mode.
Inrush measurement period:
100-milliseconds
Minimum input:
>2A on 100A range; >20A on 400A range
!
Note: AAC or Hz through the clamp and VAC through the test leads
can be measured simultaneously. However, if only AAC, Frequency
(Hz), or Inrush AAC is measured through the clamp, test leads and
thermocouples must be unplugged from the meter.
