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

3.
Touch the test probes to the diode under test. Forward
voltage will indicate 400 to 700mV. Reverse voltage will
indicate “
