Transistor tester Atmega328 (slo)

Postby Feko » 22-10-2015, 19:37

Zar je moguće da nisam stavio ovog testera na forum a prošlo godinu i pol dana :ohno:
...varijanta sa Atmega 328 mikrokontrolerom! Atmega u DIP kučištu.
Vrlo precizan, poboljšano mjerenje tiristora i trijaka..mjeri i ESR vrijednost kondezatora,
dodano kalibriranje uređaja!

fuse:
High: 0xD9, Low: 0xF7, Ex: 0xFF

Znači ovaj može i one BTA da pregleda?

Ne može sve. Struja testiranja mora biti veća od struje držanja. Maksimalna struja testranja koliko se sjećam kod ovog testera je 6mA. Oni koji zahtjevaju veću struju na gate ne mogu se testirati. Za njih je bolji onaj jednostavni tester sa par otpornika i 2 LEDice :wink:

Od 10 trijaka, 3 donja nije mogao prepoznati

...u svakom slucaju tko treba pouzdan SCR tester neka napravi nesto ovako ili sl.

Feko, jel ima neko uputstvo za ovo, kako ide kalibracija i te stvari...?
