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
2. Press MODE (if required) so DC appears on the display.
3. Insert the black test lead banana plug into the negative COM jack and
the red test lead banana plug into the positive V jack.
4. Touch the test probe tips to the circuit under test. Be sure to observe
the correct polarity (red lead to positive, black lead to negative).
5. Read the voltage in the display.

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
2. Press MODE (if required) so AC appears on the display.
