4.3.4 Continuity test and Diode test
Before taking any in circuit resistance measurement or diode test, remove
power from the circuit to be tested and discharge all the capacitors.
Continuity test
1. Insert the red test lead plug into V- jack and the black test lead plug into COM jack
and perform continuity test on the object on test (see Fig. 6 – left side). The " " is
shown at display. Buzzer emits sound if the measured resistance value is less about
25
Diode test
2. Insert the red test lead plug into V- jack and the black test lead plug into COM jack
3. 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
4. Values on the display between 0.4V and 0.7V (direct) and "OL" (reverse) indicate
correct connection while "OL" in both directions indicated an interrupted device
