Connect the black test lead to the anode and the red test lead to the cathode.
Normally, the display shows the “ OL ” symbol, indicating that the diode under test is normal.
The diode is defective if the display gives a certain voltage level.

4.3.7 Temperature Measurement (TEMP)
CAUTION
To avoid damage to instrument
Turn off the power to the circuit under test before starting measurement in order to prevent any
excessive voltage from being applied to the instrument.
Note
Optional Temperature probe is required for temperature measurement.
Temperature Probe: Thermocouple Type K
Model: 8405, 8406, 8407, 8408
Check the measurable range of respective probes.
1) Turn the function switch to the “ TEMP ” position.
2) Plug the measuring probe into the input terminals.
3) Contact the Temprature probe to the under test and then read the value
when it stabilizes.
