DC Current Measurements
WARNING:
Observe all safety precautions when
working on live circuits. Do not measure current on circuits
that exceed 600V. Measurements in the 10A range should
be limited to 30 seconds maximum every 15 minutes.
1. Set the rotary function switch to
the 10A position.
2. Insert the black test lead into the
COM input jack and the red test
lead into the 10A input jack.
3. Remove power from the circuit
under test, then open up the
circuit at the point where you
wish to measure current.
4. Touch the test lead probes in
series with the circuit being
measured. Touch the red probe
to the positive side of the circuit
and touch the black probe to the
negative side of the circuit.
5. Apply power to the circuit.
6. Read the current on the LCD display.
