Operation
1. For current measurements up to
200mA AC/DC, set the rotary
function switch to the
mA
position.
2. For current measurements up to
4000µA AC/DC, set the rotary
function switch to the
µA
position.
3. Press the
MODE
button to select AC
or DC current.The “ ” (AC) or “ ”
(DC) symbol will be shown on the
LCD display.
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 test lead probes in series
with the circuit being measured.
For DC current, touch the red probe
to the positive side of the circuit
and touch the black probe to the
negative side of the circuit.
6. Apply power to the circuit.
7. Read the current on the LCD display.
AC/DC Current Measurements
Observe all safety precautions
when working on live circuits. Do not measure current
on circuits that exceed 600V.
WARNING:
NOTE:
0.2A/600V fast acting Resettable Fuse on mA and
µA ranges. No replacement required.

Operation cont.
1. Set the rotary function switch to the
position.
2. Press the
MODE
button until the “
Ω
”
symbol appears on the display.
3. Touch the test lead probes to the
component under test. If the
component is installed in a circuit,
it is best to disconnect one side
before testing to eliminate
interference with other devices.
4. Read the resistance in on the LCD display.
Resistance Measurements
Never test resistance on a live circuit
WARNING:
Ω
1. Set the rotary function switch to the
position.
2. Press the
MODE
button until the “ “ symbol appears
on the LCD display.
3. Touch the test lead probes to the diode under test.
4. Forward voltage will indicate 0.4 to 0.7 on the
LCD display. Reverse voltage will indicate “OL”.
Shorted devices will indicate near 0 and an
open device will indicate “OL” in
both polarities.
Diode Test
Never test diodes in a live circuit.
