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
position.
2. Insert the black lead banana plug into the negative
COM
jack.
Insert the red test lead banana plug into the positive
Ω
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
Ω
, 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
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.
