Problema cleste ampermetric

Recommended Posts

Am un clampmetru AC/DC, mai exact un UT213C, si a mers pana astazi cand am incercat a masor ceva pe la masina. Defectiunea s-a produs cand l-am apropiat de fisele de la bujii. Pe DC imi arata OL, iar pe AC oscileaza aiurea, si nu masoara nimic. Celelate functii nu sunt afectate. Am cautat vreo 2 ore pe net, inclusiv pe youtube, dar n-am gasit pe nimeni sa fi avut problema mea. Exista vreo sansa sa il repar? Va multumesc!

Am gasit un condensator cu tantal, in scurt (C12 - 467A - 24hB5), ei find in total doi, ambii identici. Pe net am gasit ceva similar, 47uF, dar nu stiu ce voltaj. Ar merge si un condensator clasic in locul lui, am chiar unul de 63v? E posibil sa fie doar acel condensator dus? Am verificat si amplificatorul TI 87 I333, si nu ar fi in scurt.
