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
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. Touch the test probe tips to the
circuit or wire you wish to check.
4. If the resistance is less than
approximately 30
, the audible
signal will sound. If the circuit is
open, the display will indicate “1”.
DIODE TEST
1. Insert the black test lead banana
plug into the negative
COM
jack
and the red test lead banana plug
into the positive (diode) jack.
2. Turn the rotary switch to the
position.
3. Touch the test probes to the diode
under test. Forward bias will
typically indicate 400 to 1000.
Reverse bias will indicate “
1
”.
Shorted devices will indicate near
0 and the continuity beeper will
sound. An open device will
indicate “
1
” in both polarities.
