AC current measurements
WARNINGS
: Observe all safety precautions when working on live circuits. Do not measure
current on circuits that exceed 600 V. Measurements in the 10 A range should be limited to 30
seconds maximum every 15 minutes.
1. Set the rotary function switch to the 10 A~ position.
2. Insert the black test lead into the COM input-jack and the red
test lead into the 10 A 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.
5. Apply power to the circuit.
6. Read the current on the LCD.

DC current measurements
WARNINGS
: Observe all safety precautions when working on live circuits. Do not measure
current on circuits that exceed 600 V. Measurements in the 10 A range should be limited to 30
seconds maximum every 15 minutes.
1. Set the rotary function switch to the 10 A position.
2. Insert the black test lead into the COM input jack and the red
test lead into the 10 A 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 display.
