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 35
, the audible signal
will sound. If the circuit is open, the display will indicate “
OL
”.
