DIODE TEST
1. Connect the black test lead to the
COM
jack and the red test
lead to the “+” jack.
2. Set the function switch to
OHM/DIODE/CONTINUITY
(
Ω/
./
•)))
).
3. Make sure all the power is OFF.
4. To select diode test, touch the mode selection switch
(OHM/DIODE/CONTINUITY)
and the "
DIODE
" mark is
indicated in the left side on the display. This is diode check
mode.
When you touch the switch again, the mode changes to the
continuity test mode.
5. Next, connect the test leads to the diode be tested. When
measuring the forward voltage across diode a normal diode will
indicate 0.4V to 0.7V and the reverse voltage will indicate
"OL" (same as on open condition).
For a short-circuited diode, a value near 0 mV will be displayed.
CONTINUITY CHECK
1. Connect the black test lead to the
COM
jack and the red test
lead to the “+” jack.
2. Set the function switch to
OHM/DIODE/CONTINUITY.
3. To select continuity test, touch the mode selection switch
(OHM/DIODE/BUZZER)
and the "(
•)))
)" mark is indicated
in the left side on the display. This is continuity check mode. In
the continuity mode, a buzzer sounds when the resistance of the
circuit to be measured is less than approx.30
Ω
.
