4.6.3. Resistance (Ω) measurement
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. Set the function switch to the position.
2. Insert the black test lead plug into the negative (COM) socket
and the red test lead plug into the positive Ω jack.
3. Press the MODE button until “Ω” appears in 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. If the resistance is less than 35Ω, the audible signal will sound.
The display will also show the actual resistance in ohms.
