AC VOLTAGE MEASUREMENTS
AC VOLTAGE: 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.
WARNING: To avoid electric shock, make sure the probe tips
are touching the metal contacts inside the outlet before
assuming 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
indicate “AC” on the display.
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
negative side of the circuit.
Touch the red test probe tip to the
positive side of the circuit.
5. Read the voltage in the display.
