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 banana plug into
the negative
COM
jack.
Insert the red test lead banana plug into the

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 on the display.
CONTINUITY CHECK
WARNING
:
To avoid electric shock, never measure continuity on
circuits or wires that have live voltage passing through them.
1. Set the function switch to the
