Resistance Measurements

Warning:

TO AVOID ELECTRIC SHOCK, DISCONNECT POWER TO THE
UNIT UNDER TEST AND DISCHARGE ALL CAPACITORS BE-
FORE TAKING ANY RESISTANCE MEASUREMENTS. REMOVE
THE BATTERIES AND UNPLUG THE LINE CORDS.

1. Set the function switch to the green Ω CAP position.

2. Insert the black test lead banana plug into the

negative COM terminal.

3. Insert the red test lead banana plug into the positive Ω

terminal.

4. Press the MODE button to indicate “Ω” on the display.

5. Connect 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.

6. Read the resistance in the display.
