DIODE TESTS
1. Set the Function/Range switch to the " /
/
/ ns"
position. Use the "SHIFT" button to select the "
"
diode test.
2. Turn off power to the circuit under test. External voltage
across the components causes invalid reading.
3. Connect the red test lead to the "V " jack and the black
test lead to the "COM" jack.
4. Touch probes to the diode. A forward-voltage drop is
about 0.6V (typical for a silicon diode).
5. Reverse probes. If the diode is good, "OL” is displayed. If
the diode is shorted, "0.00" or another number is
displayed.
6. If the diode is open, "OL” is displayed in both directions.
7. Audible Indication: Less than 0.05V.
CAPACITANCE MEASUREMENTS
1. Set the Function/Range switch to the "
" position.
2. Connect the red test lead to the "
" jack and the black
test lead to the "COM” jack.
3. Touch the probes to the capacitor. Observe polarity when
measuring polarized capacitors.
4. Read the capacitance directly from the display.
5. Discharge the capacitor before taking capacitance
measurements.
6. When the capacitor to be tested is connected, if "dIS.C"
symbol indicate on LCD, it means there is voltage
existing in the tested capacitor and to be discharged
before testing.
TEMPERATURE MEASUREMENTS
1. Set the Function/Range switch to the "°C / °F" position.
Use the "SHIFT" button to select the °C or °F Temp test.
2. Remove leads and slide the Temp switch to the right to
close lead jacks
3. Plug any K-type thermocouple directly into the meter to
measure temperature.
4. Take temperature measurement using the thermocouple
probe and read the temperature from the display.
