Köszöntök Minden Kedves Tanyakedvelőt !
Vásároltam magamnak egy hibás és láthatóan hiányos GT-05 jelű 81 Wattos Gelka Labortápot. Segítséget kérek a hiányzó (vélhetően ellenállás) beazonosításához. Jó szolgálatot tenne egy kapcsolási rajz is. Minden segítséget előre is megköszönök.
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.
