4.3.5 Continuity test and Diode test

CAUTION

Before taking any in circuit resistance measurement or diode test, remove

power from the circuit to be tested and discharge all the capacitors.

Fig. 7: Taking continuity test and diode test

1. Rotate the switch on Ω position

2. Pushing MODE key and select continuity test. The symbol is shown at display

3. Insert the red test lead plug into VΩ jack and the black test lead plug into COM

jack and perform continuity test on the object on test (see Fig. 7 – left side). Buzzer

emits sound if the measured resistance value is less about 100Ω

4. Pushing MODE key and select diode test. The “ ” symbol is shown at display

5. Connect the red test leads to the anode of diode on test and the black test lead on the

cathode ones (see Fig. 7 – right side)

6. Displayed values within 0.4V and 0.7V (direct junction) and “OL” (reverse junction) are

correspondent to a correct result. A “0mV” value means a shorted device while a “OL”

indication in both side means a broken device
