3. Connect the black lead to the “COM” terminal and the red lead to “V”.
4. Place the test probes on the terminals of the component:
5. Read the measured threshold voltage of the junction indicated
on the display unit.
If the value is <40mV ±10mV an audible signal is triggered.
6. “O.L” is displayed, if the circuit is open or the threshold of the diode >3V.
