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 green
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
”.
DIODE TEST
1. Set the function switch to the green
Ω
CAP
position.
2. Insert the black test lead banana plug into the
negative
COM
jack and the red test lead
banana plug into the positive
V
jack.
3. Press the
MODE
button to indicate“ “ and
“
V
”
on the display.
4. Touch the test probes to the diode under test.
Forward voltage will typically indicate 0.400 to
0.700V. Reverse
voltage will indicate “
OL
”.
Shorted devices will indicate near 0V and an
open device will indicate “
OL
” in both
polarities.
