Diskriminacija triodnih proizvoda

Discrimination of the base of the triode: According to the schematic diagram of the structure of the triode, we know that the base of the triode is the common pole of the two PN junctions in the triode. Therefore, when judging the base of the triode, as long as the common pole of the two PN junctions is found, That is the base of the triode. The specific method is to adjust the multi-meter to the R1k block of the electric block, first place the red test lead on one foot of the triode, and use the black test lead to touch the other two feet of the triode. If it is fully connected twice, the red test lead The foot placed is the base of the triode. If it is not found once, change the red test lead to the other foot of the triode and test it twice; if it is not found, change the red test lead again and test it twice. If you haven't found it yet, use the black test lead to place it on one foot of the triode, and use the red test lead to test it twice to see if it is fully connected. If it fails once, then replace it. In this way up to 12 times, the base can always be found.

Diskriminacija tipova tranzistora: Postoje samo dvije vrste trioda, naime PNP tip i NPN tip. Prilikom ocjenjivanja samo trebate znati je li osnova P-tip ili N-tip. Kada koristite blok s više-metara R1k, crni ispitni kabel predstavlja pozitivni pol napajanja. Ako je crni ispitni kabel spojen na bazu, on je uključen, što pokazuje da je baza tranzistora P-tipa, a tranzistor NPN-tipa. Ako je crveni ispitni kabel spojen na bazu, to znači da je baza trioda tipa N-, a trioda je tipa PNP-.
