RESISTANCE 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 Ω position.
2. Insert the black test lead into the negative COM terminal
and the red test lead into the positive Ω terminal.
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
CONTINUITY CHECK
WARNING: To avoid electric shock, never measure
continuity on circuits or wires that have voltage on them.
1. Set the function switch to the

check.
5. If the resistance is less than approximately 150Ω, the
audible signal will sound. If the circuit is open, the display
will indicate "OL".
