(COM)
jack
Insert the red test lead banana plug into the positive (
)
jack.

check.
4. If the resistance is less than approximately
audible signal will sound. If the circuit is open, the display

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 voltage will indicate 400 to 700mV.
Reverse voltage will indicate “
I
”. Shorted devices
will indicate near 0mV. Shorted devices will
indicate near 0mV and an open device will indicate
“
I
” in both polarities.
