• 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.
• 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.
6-4 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 V 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.
•Set the function switch to the highest V AC position
• Insert the black test lead banana plug into the negative(COM)jack.
Insert red test lead banana plug into the positive(V)jack.

• 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.
• 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.
6-5 DC Current Measurements
CAUTION: Do not make current measurements on the 10 A scale for longer than 30
seconds. Exceeding 30 seconds may cause damage to the meter and/or the test leads.
• Insert the black test lead banana plug into the negative (COM) jack.
• For current measurements up to 200 mA dc, set the function switch to the highest DC
mA position and insert the red test lead banana plug into the(mA)jack.
• For current measurements up to 10 A dc, set the function switch to the 10 A range and
insert the red test lead banana plug into the (10 A)j ack.
• Remove power from the circuit under test, then open up the circuit at the point where
you wish to measure current.
• 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.
