4.3. AC Voltage Measurement
1. Set the function switch to the
V
~
Position.
2. Insert the black test lead banana plug into the negative
COM
jack.
3. Insert the red test lead banana plug into the
Positive
jack.
4. Read the voltage on the display.
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.
