Amps AC (AAC) True RMS (50-60Hz)
Test isolated power lines. Press SELECT once on VAC/AAC/Hz position.
Read AAC in upper display and VAC on the lower display at the same time.

Frequency (Hz) Through Clamp
Measure Hz on variable frequency drive motors. Turn dial to VAC/AAC/
Hz and press SELECT twice. Hz will show in upper display and VAC on the
lower display at the same time.
Range:
10Hz to 400Hz
Resolution:
0.1Hz
Accuracy:
±(0.1% + 5)
Minimum current range:
>7AAC (10 to 100Hz); >20AAC (100 to
400Hz) on 100AAC range; >25AAC (10 to 400Hz) on 600AAC range.
Overload Protection:

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 Inrush Mode.
3 Clamp jaw around the motor’s start wire.
4 Turn motor on. The starting amp draw will hold on the upper display.
5 Press INRUSH to clear captured reading. Press INRUSH for 2 seconds to
exit.
Inrush measurement period:
100-milliseconds
Minimum input:
>2A on 100A range; >20A on 600A 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.
