Sziasztok
Van egy ilyen régi műszerem nagyon hozzám nőtt, jó lenne megjavítani.
Sajnos minap egy kis víz került a kapcsolóhoz, azonnal szétszedtem, kitakarítottam, kiszárítottam.
Viszont elkezdte, hogy dióda állásban nem "1 "-et mutat a kijelző, hanem 100mV/000mV össze- vissza. Itt találtam kapcsolási rajzot, de esetleg valaki találkozott ilyen hibával?
Az összes tisztítást megcsináltam, átforrasztottam az egészet.
Köszi a segítséget
Szabi
Üdv mindenkinek !
Sokat beszélgettünk már a kondenzátorok vizsgálatáról.
Ami vagy jó vagy nem.
De mi van akkor ha a digi műszer jónak méri és mégsem ?
Találtam egy egyszerű vizsgálati módszert.
Nekem újdonság , pedig kézenfekvő lett volna.
Persze nem akarok más tollával ékeskedni ! a Neten találtam.
Hello everyone.
I can't use all of the track settings on my CS-1021 oscilloscope.
"Astig" must be turned fully clockwise, "Intensity" does not work, "Focus" must be turned fully clockwise, "Trace Rotation" is the only command that works.
What can I check?
Thank you
