Sziasztok,
A címben szereplő műszer javításához szeretnék műszaki támogatást kérni. A készülék rajzát megtaláltam a Interneten keresgélve a 2003/1 Hobby Elektronika folyóiratban. A kapcsolási rajzon kívül keresem a szervizkönyvét esetleg részletező leírás a beállításáról, milyen jellel kell meghajtani, benne milyen jelszinteket kell beállítani, stb...
Köszönöm a segítséget!
Üdv
M.

Sziasztok !
120DA tipusú 50 mikroamperes DEPREZ mérőműszer lengőtekercse megszakadt, javítani nem tudom, Ki tudnám cserélni másik,
méretben azonos műszerre az azonban 100 mikroamper végkitérésű.
Ez a műszer a készülékbe beépítve csak a mért értékek felét mutatja.
Műszererősítő kapcsolási rajzban kérném segítségeteket, lehetőleg olyat keresnék amihez nem kell kettős tápfeszültséget
használni.
Köszönettel nagyis
Hello to everybody,
I have bought a defective Gould oscilloscope DSO420. At the beginning of the repair the power fuse was blown immediately after inserting the power plug: The RF-filter connector was shorted. Okay, ignore the RF-filter for now.
Some leaked capacitors were within the power supply, all renewed as well as the NiMh accumulator.
Now most of the scope is running:: All LED at the front as well they are switchable and the screen of the scope was lightened th but only a vertical line is shown. No horizontal deflection at all.
The circuit I have attached, all semiconductor are renewed, no change. The electrolytics are renewed, no change. Allways a vertical stroke. Does anyone have an idea?
Regards from Hamburg
Jens
