CONTINUITY CHECK
WARNING: To avoid electric shock, never measure continuity on circuits that have a voltage
potential.
1.
Set the function switch to the
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.
4.
Touch the test probe tips to the circuit or wire you wish to check.
5.
If the resistance is less than approximately 100Ω the audible signal
will sound. If the circuit is open, the display will indicate "1___".
DIODE TEST
1.
Set the function switch to the
2.
Insert the black test lead banana plug into the negative COM
jack and the red test lead banana plug into the positive
3.
Touch the test probes to the diode under test.
4.
A good diode will indicate approx. 700 ohms for the forward test
and "1___" for the reverse test.
5.
A shorted diode will indicate the same value of resistance in both
the reverse and forward test directions. An open diode will
indicate "1___" in both test directions.
