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
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
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.
