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.
I 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
I
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.
4.
Read the voltage in the display. Reset the function
switch to successively
lower V AC positions to
obtain a higher resolution reading. The display will indicate the proper
decimal point and value.
