negative COM jack.
Insert the red test lead banana plug into the
positive Ω jack.
3. Press the MODE button to indicate "Ω" on the
display.
4. Touch the test probe tips across the circuit or
part under test. It is best to disconnect one side
of the part under test so the rest of the circuit
will not interfere with the resistance reading.
5. Read the resistance on the display.
