1. Turn the rotary function switch to
the
Ω
CAP
position.
2. Press the MODE button until the “ ”
symbol appears on the LCD display.
3. Insert the black test lead into the negative
COM
input jack and the red test lead into
the positive
Ω
input jack.
4. Touch the test probes to the diode
under test. Forward voltage will indicate
0.4 to 0.7V. Reverse voltage will indicate
“
OL
”. Shorted devices will indicate near
0V and an open device will indicate “
OL
”
in both polarities.
Forward test Reverse test
Continuity Test
Never test continuity on a live circuit.
WARNING:
1. Set the rotary function switch to the
Ω
CAP
position.
2. Press the
MODE
button until the “ ” symbol
appears on the LCD display.
3. Insert the black test lead into the
negative COM input jack. Insert the red
test lead into the positive
Ω
input jack.
4. Touch the test probe tips to the circuit or
wire you wish to check.
5. If the resistance is approximately 30
Ω
or
less, an audible tone will sound. If the circuit
is above 400
Ω
, the LCD display will indicate
“
OL
”. The resistance will be shown on the
LCD display if it is below 400
Ω

WARNING:
Operation
1. Set the rotary function switch to
the
Ω
position.
2. Press the
MODE
button until “
nF
”
appears on the LCD display.
3. Insert the black test lead into the negative
COM
input jack and the red test lead into
the positive
CAP
input jack.
4. Touch the test leads to the capacitor
being tested.
5. Read the capacitance value on the LCD display.
The meter will automatically adjust the reading
ranges between pF, nF and uF. Large capacitors
may take up to a minute to get a stable reading.
Capacitance Measurements
Safely discharge capacitors
before taking capacitance measurements.
1. Set the rotary function switch to the
Hz%
position.
2. Press the
Hz%
button to select frequency or
duty cycle.
“Hz”
or
“%”
will appear on the
LCD display.
3. Insert the black test lead into the negative
COM
input jack and the red test lead into the
positive
Hz%
input jack.
4. Touch the test probe tips to the circuit under
test.
5. Read the frequency or % duty cycle on the
LCD display.
