AC True RMS Current Measurement
Warning
Ensure that the test leads are disconnected from the meter
before making current measurements.
1. Set the function switch to
1000A~
or
400A~
or
40A~
range position,
and make sure that the current under test does not exceed the upper
limit of the measuring range you have selected
2. Press the
MODE
button to select the AC Current range. The meter
automatically defaults to DC current
3. Press the trigger to open up the transformer jaws and clamp around
the single conductor under test.
4. Read the display.
Notes:
• During current measurements keep the transformer jaws fully closed,
otherwise this will affect the accuracy of the measurement.
• When large currents the transformer jaws may buzz. This is not a fault
and does not affect the accuracy of the reading.
• The meter is set to default to “Auto Range” mode.
• Pressing the
pEAK
hold button will allow the user to record the peak
maximum and minimum readings on the AC volt range. See page 17 for
