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 batteries and unplug
the line cords.
1. Set the rotary function switch to the green

position.
2. Insert the black test lead banana plug into the negative COM
jack and 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 in the display.
Continuity Check
WARNING: To avoid electric shock, never measure continuity on
circuits or wires that have voltage on them.

4. Touch the test probe tips to the circuit or wire you wish
to check.
5. If the resistance is less than approximately 35 Ω , the audible
signal will sound. If the circuit is open, the display will
indicate “OL”.
