4.3.4. Diode test

CAUTION

Before taking diode test measurements in circuit remove power from the

circuit being tested and discharge all capacitors.

Fig. 5: Using the instrument for diode test

1. Switch on Ω CAP

2. Pressing the MODE key until the symbol

is shown at display to meaning the diode

test

3. Insert the test leads into the jacks, the red plug into VΩTempHz%CAP jack and

black plug into COM jack (see Fig. 5)

4. Connect the test leads to the diode under test observing the proper polarities indicated

in Fig. 5. The threshold voltage value expressed in mV under this situation is displayed

5. If the threshold voltage value is 0V the diode P-N junction is shorted circuit

6. If the message "O.L" is displayed the diode terminals are reversed, the diode P-N

junction is damaged
