4.3.5. Diode test
Before attempting any resistance measurement, cut off power supply from
the circuit to be measured and make sure that all capacitors are discharged,
if present.
1. Select position
2. Press the MODE key to select
3. Insert the red cable into input terminal VHz%
(HT62) and the black cable into input terminal COM.
4. Position the leads at the ends of the diode to be tested (see Fig. 6), respecting the
indicated polarity. The value of directly polarized threshold voltage is shown on the
display.
5. If threshold value is equal to 0mV, the P-N junction of the diode is short-circuited.
6. If the display shows the message
respect to the indication given in Fig. 6 or the P-N junction of the diode is damaged.
