Continuity Check; Diode Test - FLIR Extech Instruments 410 User Manual

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
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. Touch the test probe tips to the circuit or wire you wish to
check.
4. If the resistance is less than approximately 150Ω, 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
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.
