Operating Instructions
WARNING: Risk of electrocution. High-voltage circuits, both AC and DC, are very
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.

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. Set the function switch to the green 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 VOLTAGE (FREQUENCY, DUTY CYCLE) MEASUREMENTS
WARNING: Risk of Electrocution. The probe tips may not be long enough to contact the
live parts inside some 240V outlets for appliances because the contacts are recessed
deep in the outlets. As a result, the reading may show 0 volts when the outlet actually
has voltage on it. Make sure the probe tips are touching the metal contacts inside the
outlet before assuming that no voltage is present.
CAUTION: Do not measure AC voltages if a motor on the circuit is being switched ON or
OFF. Large voltage surges may occur that can damage the meter.
1. Set the function switch to the green VAC/Hz/% position.
2. Insert the black test lead banana plug into the negative COM jack.
Insert red test lead banana plug into the positive V jack.
3. Touch the black test probe tip to the neutral side of the circuit.
Touch the red test probe tip to the "hot" side of the circuit.
4. Read the voltage in the display.
5. Press the HZ/% button to indicate "Hz".
6. Read the frequency in the display.
7. Press the Hz/% button again to indicate "%".
8. Read the % of duty cycle in the display.

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 6000µA DC, set the function switch to the yellow µA
position and insert the red test lead banana plug into the µA/mA jack.
3. For current measurements up to 600mA DC, set the function switch to the yellow mA
position and insert the red test lead banana plug into the µA/mA jack.
4. For current measurements up to 20A DC, set the function switch to the yellow 10A/HZ/%
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 up the circuit at the point where you
wish to measure current.
