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
position
2. Pushing
MODE
key and select continuity test. The
symbol is shown at display
3. 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. 7
– left side). Buzzer
emits sound if the measured resistance value is less about 100
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
