Diode Test
1. Turn the rotary function switch to Press the "FUNC.” key to cycle through from resistance
(to continuity to capacitance) to diode function.
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.
Warning
To avoid electrical shock when testing diodes in a circuit, make sure the power to the circuit is turned
off and all capacitors are discharged.
To avoid damaging the instrument or equipment, do not input a voltage greater than 10V.
