DIODE TEST
1. Set the function switch to the green
Ω
CAP
position.
2. Insert the black test lead banana plug into the
negative
COM
jack and the red test lead banana
plug into the positive
V
jack.
3. Press the
MODE
button to indicate and
V
on the
display.
4. Touch the test probes to the diode under test.
Forward voltage will typically indicate 0.400 to
0.700V. Reverse voltage will indicate “
OL
”. Shorted
devices will indicate near 0V and an open device will
indicate “
OL
” in both polarities.
TEMPERATURE MEASUREMENTS
1. Set the function switch to the green
Temp
position.
2. Insert the Temperature Probe into the input
jacks, making sure to observe the correct
polarity.
3. Press the
MODE
button to indicate
ºF
or
ºC
4. Touch the Temperature Probe head to the part
whose temperature you wish to measure.
Keep the probe touching the part under test
until the reading stabilizes (about 30 seconds).
5. Read the temperature in the display.
Note:
The temperature probe is fitted with a type K mini connector. A mini
connector to banana connector adaptor is supplied for connection to
the input banana jacks.
