Salut!Am facut rost de un multimetru digital de tip DT-9205A. Problema este ca buzzer-ul nu scoate un sunet continu ci mai mult paraie. S-a mai intalnit cineva cu aceasta problema?!? As fi recunoscator pt. orice sfat...Multumesc

poate fi buzzer-ul (discul ala ca la ceasurile cu melodii) sau buffer-ul care la astea e un tranzistor MOS-FET

Sincer nu l-am desfacut inca, dar am postat acest subiect deoarece m-am gandit ca poate s-a mai lovit cineva de aceasta problema. Oricum o sa tin cont de sfatul tau si pe viitor o sa verific si buzzzer-ul si MOS-FET-ul.Multumesc pt sfat!

Am rezolvat problema. O rezistenta de tip SMD nu era lipita bine la un capat. Deh... li se mai intampla "pana si chinezilor" :tonqe: Ma bucur ca nu a fost ceva mai grav.
