Sziasztok ! Fent nevezet szkóp hibás ként kaptam szeretném meg javítani De nem vagyok jártas szkóp javításban Rajz alapján sikerült a tápot megjavítani Megvannak a feszek 15+ 15- 110v 40v ua723ic mind 3 cserélve Tr1 Tr2 Tr3 tranyo csere után, szeretnénk segítséget kérni hogy tovább Teszek fel képet
Üdv!
Kicsit más téma, ebben szeretnék segítséget a szakértőktől.
TR 9178 kettős 2x40V/2A tápegység egyik oldalát javítani kéne.
Ma sikerült szert tennem egy ilyenre, egy TR1669 asztali multiméterrel egyetemben.
A tápegysége egyik oldala halott.
Akkut akartak vele tölteni, amit nem sikerült mert megadta magát.
Van ilyenem mindegyikből, de olyan jó vétel lett, amit nem lehetett ott hagyni.
(Az érdekes mindegyiknél külsőre is van eltérés, úgy látszik azt raktak bele ami éppen kéznél volt.)
Kérdésem, mik szoktak elszállni, mennyire javítható, kb mibe fáj, beszerezhetők e az alaktrészek.
feléleszteném, már ha nem egy jó készülék árába kerül.
Gépkönyvem ha igaz a másikhoz van nyomtatott, de persze azt nem lelem, majd itt szét nézek.

nem tudja véletlenül valaki, hogy tatabánya szükebb vagy tágabb környékén hol lehet szkopkábelt venni? 1db egyszerü mezei 100mhz-s 1-10 osztoval megfelelne. lehetöleg ne aranyárban. az nem lenne baj ha szilikon lenne.
Hi,
A friend offered Oscilloscope UNAOHM G4020 = BECKMAN 9020 = Voltcraft_2040
In first hours worked ok ...
I saw the 0,2 V 1000Hz and other signal in the cinescop.
But now I only see 1 or 2 dots (channel 1 or both or ch 2).
I can move the dots UP and DOWN, LEFT and RIGHT so the screen - cinesc. is working.
I test the trigger, connect CAL 0,2V 1KHz to ch 1 or 2 and the dot go up - down, invert, etc.
A sinos. wave, I can rotate TRIG LEVEL and the dot follow the wave.
But I can't see the wave in display.
Some examples of scope:
youtube.com/watch?v=3nBYp1pN40U
youtube.com/watch?v=fPq1KgQ5ggQ
youtube.com/watch?v=5osskamWJHg
Manual and schemat. I have the French and Germany version.
