5.5. DIODE TEST AND CONTINUITY TEST
CAUTION
Before taking diode test measurements in circuit remove power from the
circuit being tested and discharge all capacitors.
Fig. 6: Using the instrument for Diode test and Continuity test
1. Switch on
position
2. Press the MODE key until the symbol “
” is shown at display
3. Insert the test leads into the jacks, the red plug into
mAµAVHz% jack and
black plug into COM jack
4. Connect the test leads to the diode under test observing the proper polarities (see Fig.
6 – right part). The threshold voltage value under this situation is displayed
5. If the threshold voltage value is 0V the diode P-N junction is shorted circuit
6. If the message "O.L" is displayed the diode terminals are reversed, the diode P-N
junction is damaged
7. Press the MODE key until the symbol “
” is shown at display to meaning the continuity
test and connect the meter as resistance measurement (Fig. 6 – left part). Buzzer emits
sound if the measured resistance value is <50
8. For HOLD function refer to § 4.2
