DC VOLTAGE MEASUREMENTS
DC CURRENT MEASUREMENTS
AC 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.
CAUTION:
Do not make current measurements on the 10A scale for longer
than 30 seconds. Exceeding 30 seconds may cause damage to the meter
and/or the test leads.
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.
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.
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.
1. Insert the black test lead banana plug into the
negative (COM) jack.
2. For current measurements up to 200mA DC, set the
function switch to the highest DC mA position and
insert the red test lead banana plug into the (mA)
jack.
3. For current measurements up to 10A DC, set the
function switch to the 10A range and insert the red
test lead banana plug into the (10A) jack.
4. Remove power from the circuit under test, then
open up the circuit at the point where you wish to
measure current.
5. 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.
6. Apply power to the circuit.
7. Read the current in the display. For mA DC measurements, reset the
function switch to successively lower mA DC positions to obtain a higher
resolution reading. The display will indicate the proper decimal point and
value.
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.
