4.3.6. Diode test

CAUTION

Before taking diode test on remove power from the circuit being tested and

discharge all capacitors.

Fig. 7: Using the instrument for Diode test

1. Selecting the position

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

into COM jack

3. Connect the test leads to the diode under test observing the proper polarities (see Fig. 7).

The threshold voltage value of direct polarization is shown at display. The meter

displays the diode voltage to approximately 0.4 ~ 0.9V for good junction.

4. If the message “ O.L." is displayed the diode terminals are reversed or the diode P-N

junction is damaged.

5. For HOLD function, Minimum and Maximum value measurement and Relative measure

please refer to § 4.2.
