AC/DC CURRENT MEASUREMENTS
CAUTION: Do not make 20A current measurements for longer than 30 seconds. Exceeding 30 seconds may
cause damage to the meter and/or the test leads.
1. Insert black test lead banana plug into the negative COM jack.
2. For current measurements up to 5000µA DC, set the function switch to the µA position
and insert the red test lead banana plug into the µA/mA jack.
3. For current measurements up to 500 mA DC, set the function switch to the mA position
and insert the red test lead banana plug into the µA/mA jack.
4. For current measurements up to 10A DC, set the function switch to the 10A/HZ/% position
and insert the red test lead banana plug into the 10A jack.
5. Press the MODE button to indicate “DC” or “AC” on the display.
6. Remove power from the circuit under test, then open up the circuit at the point where you
wish to measure current.
7. Touch the black test probe tip to the negative side of the circuit. Touch the red test probe
tip to the positive side of the circuit.
8. Apply power to the circuit.
9. Read the current in the display.
RESISTANCE MEASUREMENTS
WARNING: To avoid electric shock, disconnect power to the unit under test and discharge all capacitors before
taking any resistance measurements. Remove the batteries and unplug the line cords.
