YIHUA-937D Repair
#24
Mislim da si u pravu multimetar je star 10godina ako ne i vise a to je MASTECH MY68

Spojio sam sve kako je bilo i vrlo čudna stvar se događa...

- kada spojim 24VAC za trijak i 12VAC za elektroniku ništa nema na uređaju ne pali se...odspojim sve sa mreznog napona i toroid je topao..dakle negdje je pretpostavljam problem kod trijaka tj djela za grijač na PCB-u

- kada spojim samo 12VAC koji sluzi za elektorniku display se upali i prikaze S - E sto znaci prikljuci lemilicu...e lemilicu nisam prikljucio jer je otpojeni 24VAC...znaci moram da cackam oko tih 24VAC na PCB-u...jel mozda zna gdje da pocnem? Mislio sam testirati trijak dal nije u kratkom spoju kao i optocoupler MOC3041...jeli ko zna kako se testira optocoupler? za trijak imam tester komponenti (ona jeftina sprava od kineza spojio sam na nju trijak i pokazujemi mi da je trijak ali sumnjam da taj detektor komponenti dobro pokazuje dakle kako se ispituje trijak BT137 i MOC3041?

Zahvaljujem.

EDIT:

Gledajuci HAKKO 937 datashet S-E znaci Senzor-Error...znaci moram da vidim sutra na PCB-u oko LM358 mora da je tu nesto u kratkom spoju...posto kad se spoji 24VAC toroid se malo ugrije za kratko vrijeme...cim nadjem javljam.
