DC VOLTAGE MEASUREMENTS
CAUTION:
Do not measure DC 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 DC position.
2. Insert the black test lead banana plug
into the negative (COM) jack.
Insert the 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 DC positions to obtain 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.
