Operating Instructions
NON-CONTACT VOLTAGE (NCV)
WARNING: Always test the NCV function on a know live circuit before use
1. Turn the rotary switch to any measurement position
2. Hold the top of the meter very close to the voltage source as shown.
3. If voltage is present, the LED above the display will glow and the meter will
buzz.
NOTE: The detector is designed with high sensitivity. Static electricity or other
sources of energy may randomly trip the sensor. This is normal operation.
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 highest VAC 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 negative side of the circuit.
Touch the red test probe tip to the positive side of circuit.
4. Read the voltage in the display.
