a higher resolution reading. The display will indicate
the proper decimal point and value. If the polarity is
reversed, the display will show (-) minus before the
value.
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 V AC 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 the circuit.
