4.3.7. Diode test and continuity test

CAUTION

Before taking resistance measurements in circuit remove power from the

circuit being tested and discharge all capacitors.

Fig. 8: Diode test and continuity test

1. Turn the selector on / .

2. Insert the test leads into the jacks, the red plug into HzVA jack and the black

plug into COM jack (Fig. 8).

3. Connect the red lead to the positive side (anode) of the diode and the black lead to the

negative side (cathode). The meter displays the diode voltage to approximately 0.4 ~

0.9V for good junction.

4. Reverse the connections and measure the voltage across the diode again. The

message “OL" on the display corresponds to a correct junction.

5. The continuity test is always active and the test is performed using the test leads in the

same way of resistance measurement (refer to paragraph 4.3.6). The buzzer is on for

resistance values <500.
