RESISTANCE MEASUREMENTS
WARNING:
To avoid electric shock, disconnect power to the
unit under test and discharge all capacitors before taking any
resistance measurements. Remove the battery and unplug the
line cords.
1. Set the function switch to the
highest
Ω
position.
2. Insert the black test lead banana
plug into the negative
COM
jack.
Insert the red test lead banana
plug into the positive
Ω
jack.
3. 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.
4. Read the resistance in the display
and then set the function switch to
the lowest
Ω
position that is greater
than the actual or any anticipated
resistance.
