AC/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. Rotate the function switch to the
V
AC
or 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.
AC/DC CURRENT MEASUREMENTS
1. Insert the black test lead banana plug into the negative
COM
jack.
2. Press the
MODE
button to indicate “
DC
” or “
AC
” on the display.
3. For current measurements up to 2000µA, set the function switch to the
µA
position
and insert the red test lead banana plug into the
µA/mA
jack.
4. For current measurements up to 200 mA DC, set the function switch to the
mA
position and insert the red test lead banana plug into the
µA/mA
jack.
5. For current measurements up to 10A DC, set the function switch to the
10A
position
and insert the red test lead banana plug into the
10A
jack.
6. Connect the test leads in series with the circuit under test.
7. Apply power to the circuit.
8. Read the current in the display.
RESISTANCE MEASUREMENTS
WARNING:
To avoid electric shock, disconnect power to the unit under test and discharge all
capacitors before taking any resistance measurements. Remove the batteries and unplug the line
cords.
1. Rotate the function switch to the
Ω
position.
2. Insert the black test lead banana plug into the negative
COM
jack.
Insert the red test lead banana plug into the positive
jack.
3. Touch the test probe tips across the device under test.
4. Read the resistance in the display.
