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 function switch to the
Ω
CAP
position.
2. Insert the black test lead banana plug into
the negative
COM
jack.
Insert the red test lead banana plug into
the positive
jack.
3. Press the
MODE
button to indicate
“
"
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.
1. Set the function switch to the
Ω
CAP
position.
2. Insert the black lead banana plug into the
negative
COM
jack.
Insert the red test lead banana plug into
the positive
jack.
3. Press the
MODE
button to indicate”
"
and “
Ω”
on the display
4. Touch the test probe tips to the circuit or
wire you wish to check.
5. If the resistance is less than
approximately 100
, the audible signal
will sound. If the circuit is open, the
display will indicate “
OL
”.
