Resistance Measurement
NOTE:
Remove power before making resistance measurements.
1. Insert the black test lead into the negative COM terminal and the red
test lead into the positive V terminal.
2. Set the rotary function to the
Ω
position.
3. Press the
SELECT
button to switch to resistance measurement
mode (
Ω
).
4. Connect the test leads in parallel to the circuit under test. It is best to
disconnect one side of the device under test so the rest of the circuit
will not interfere with the reading.
5. The LCD will display the reading.
Continuity Measurement
1. Insert the black test lead into the negative COM terminal and the red
test lead into the positive V terminal.
2. Set the rotary function to the
Ω
position.
3. Press the
SELECT
button to switch to continuity
measurement mode (
).
4. Connect the test leads in parallel to the circuit under test.
5. If the resistance is ≤30Ω, the circuit is in good condition and the
device will emit a continuous buzzer sound.
NOTE:
If the measured resistance is ≥70Ω, the device will not emit a
buzzer sound.
Diode Test
1. Insert the black test lead into the negative COM terminal and the red
test lead into the positive V terminal.
2. Set the rotary function to the
Ω
position.
3. Press the
SELECT
button to switch to diode test mode (
).
4. Connect the red probe to the diode anode, and the black probe to
the diode cathode.
