AC Voltage Measurements
WARNING:
Risk of Electrocution. The probe tips may not
be long enough to contact the live parts inside some 230V
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.
-
Set the function switch to the VAC position.
-
Insert the black test lead banana plug into the
negative COM jack. Insert red test lead banana
plug into the positive V jack.
-
Read the voltage in the main display.
