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 the black test lead banana plug into the negative COM jack.
2. For current measurements up to 4000µA DC;
Set the function switch to the µA position and insert the red test lead
banana plug into the µA jack.
3. For current measurements up to 400mA DC;
Set the function switch to the mA position and insert the red test lead
banana plug into the mA jack.
4. For current measurements up to 10A DC;
Set the function switch to the 10A position and insert the red test lead
banana plug into the 10A jack.
5. Press the MODE button to indicate “DC” on the display.
6. Remove power from the circuit under test, then open 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.
AC 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 the black test lead banana plug into the negative COM jack.
2. For current measurements up to 4000µA AC;
Set the function switch to the µA position and insert the red test lead
banana plug into the µA jack.
3. For current measurements up to 400mA AC;
Set the function switch to the mA position and insert the red test lead
banana plug into the mA jack.
4. For current measurements up to 10A AC;
Set the function switch to the 10A position and insert the red test lead
banana plug into the 10A jack.
5. Press the MODE button to indicate “AC” on the display.
6. Remove power from the circuit under test, then open 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.
