Fig. 5: 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 VmAμA jack and black plug into COM jack
4. Connect the test leads to the diode under test observing the proper polarities (see Fig. 5 – 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. 5 – left part). Buzzer emits sound if the measured resistance
value is <40
8. For HOLD function refer to chapter 4.2
