Diode Test
Do not enter a voltage above 10 V! Make sure that the power supply to the circuit is disconnected
and all capacitors are discharged.
1. Turn the rotary function switch to . Press the "FUNC." key 2 times until appears on the
display.
2. Remove power from the circuit being tested.
3. Connect the black test lead to the COM terminal and the red test lead to the INPUT terminal.
4. Connect the black test lead to the cathode side and the red test lead to the anode side of the
diode being tested.
5. Read forward bias voltage value on the LCD.
6. If the polarity of the test leads is the reverse
of the diode polarity, the LCD reading shows " OL”.
This can be used for distinguishing the anode side
and cathode side of a diode.
Test voltage approx. 2V
Overload protection: 250V
