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. 6: 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. 6 – left side). Buzzer
emits sound if the measured resistance value is less about 150Ω
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. 6 – right side). The correspondent threshold voltage of P-N
junction is showed on display
6. Reverse position of test leads to reading inverse polarization voltage
