Data Hold
The Data Hold function freezes the reading in the display. Press the HOLD button to switch Data
Hold ON/OFF. When the Data Hold mode is active the display will show the H icon.
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 V position.
2. Press the SELECT button to switch to DC if necessary.
3. Insert the black test lead banana plug into the negative COM jack.
Insert the red test lead banana plug into the positive V jack.
4. 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.
5. Use the RANGE button to manually range the reading. Press and
hold the RANGE button to return to Auto Range Mode. Read the
voltage in the display.
AC VOLTAGE 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 V position.
2. Press the SELECT button to switch to AC if necessary.
3. Insert the black test lead banana plug into the negative COM jack.
Insert red test lead banana plug into the positive V jack.
4. 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.
5. Read the voltage in the display.
6. Use the RANGE button to manually range the reading. Press and
hold the RANGE button to return to Auto Range Mode.
