Operating Instructions

WARNING: Risk of electrocution. High-voltage circuits, both AC and DC, are extremely dangerous

and should be measured with great care.

1. ALWAYS turn the function switch to the OFF position when the meter is not in use.

2. If “OL” appears in the display during a measurement, the value exceeds the range you have

selected. Change to a higher range.

AC/DC VOLTAGE MEASUREMENTS

CAUTION: Do not measure DC voltages if a motor on the circuit is being switched ON or OFF.

Large voltage surges may occur that can damage the meter.

1. Rotate the function switch to the VAC or VDC position.

2. Insert the black test lead banana plug into the negative COM jack. Insert the red

test lead banana plug into the positive V jack.

3. 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.

4. Read the voltage in the display.

AC/DC CURRENT MEASUREMENTS

1. Insert the black test lead banana plug into the negative COM jack.

2. Press the MODE button to indicate “DC” or “AC” on the display.

3. For current measurements up to 2000µA, set the function switch to the µA position

and insert the red test lead banana plug into the µA/mA jack.

4. For current measurements up to 200 mA DC, set the function switch to the mA

position and insert the red test lead banana plug into the µA/mA jack.

5. 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.

6. Connect the test leads in series with the circuit under test.

7. Apply power to the circuit.

8. Read the current in the display.
