DC 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. The meter automatically
defaults to DC Current.
2. Press the
DC ZERO
button once, the
sign will appear on the LCD
indicating Range is zero.
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 it 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.
