Va salut cu respect, am achizitionat un Megoohmetru tip IRME-500/1000v alimentat la 9v stas4640-74 fabr.1981.aparatul nu functioneaza datorita umiditatii mari si eventuale scurturi,din transformator,pe care vreau sa l rebobinez. ma poate ajuta careva, cu schema acestuia.

Multumesc domnului Constantin Soldan ,pt. schema megoohmetrului tip IMRE 500/1000v .Am reusit sa rebobinez transformatorul aparatului,(bobinajul era VERDE din cauza oxidului de cupru in interiorul transformatorului). Am inlocuit si ce i doi tranzistori , AC 180 care aveau piciorusele mincate de rugina, cu BD 136. Acum aparatul functioneaza perfect. Ar fi fost o lipsa de respect, din partea mea,sa nu i fi multumit domnului Constantin Soldan , satisfactia e mare. cu aceasta ocazie , salut pe toata lumea ce navigheaza in acest moment pe FORUM.
