Menguji Dioda Menggunakan Multi Meter
- Turn the switch on the Ohm, let R x 1K
- Investigators Attach the red to the cathode (+) and black Investigators at the anode (-) diode
- If the needle moves multimeter that is good, but if the needle does not move means diodes have been broken or damaged
- Then a black investigator then attached to the cathode (+) and red pencolok attached to the anode (-). When the needle multimeter silent, means the diode is in good condition but if the move means that the diode has been leaked (damaged)
When the supply voltage is reversed the diode is said to be in reverse biased condition. Here there is no conduction at lower voltage values .If we increase the voltage value further ,it is observed that at a voltage the current sharply increases due to the breakdown of the P-N junction. This damages the device.
