Amps AC (AAC) True RMS (50-60Hz)
Test isolated power lines. Press SELECT on VAC/100AAC/Hz or
VAC/600AAC/Hz position. Read AAC in upper display and VAC on the lower
display. For AC current <100AAC, select VAC/100AAC/Hz switch position
and for AC current >100AAC, select the VAC/600AAC/Hz switch position.
Range: 100A, 600A Resolution: 0.01A Crest factor: ≤ 3
Accuracy: ±(2.5% + 15) 100A, ±(2.0% + 10) 600A
Minimum Input Current Range: >20 digits
Overload Protection: 600AAC Jaw Opening: 1.2in (30 mm)
Frequency (Hz) Through Clamp
Measure Hz on variable frequency drive motors. Turn dial to either
VAC/100AAC/Hz or VAC/600AAC/Hz position 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.

Amps AC (AAC), Frequency (Hz) through the clamp and Inrush AAC current
is measured in the VAC/100AAC/Hz or VAC/600AAC/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/100AAC/Hz or VAC/600AAC/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 100AAC 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.
