Tisztelt tagság!
Mellékelek egy képet ami alapján jelenleg ellenőrzöm a csőteszterem paramétereit, hátha akad olyan köztetek aki tudja a választ.
A szép zölddel bekarikázott rész érdekes, szkóppal mérve a frekvencia tökéletes, viszont a 450mV amit írnak hogy értendő vajon? Vpp? Efffektív? jelenleg, 2.24v Vpp van jelen ott, Rms 1.19 volt.

Sziasztok!
A kispesti ESR-03 tip. műszerem nem mér csak kapacitást.
Az esr mérő része állandóan 0-t ír ki.
Tud-e valaki valami jót mondani rá?
Köszönöm!
Üdv. Gyuri
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

Helo.Egy ilyen frekimérőt szeretnék ősszedobni,vagyis 0-100Khz tartományban,de ha lehetséges lenne PIC nélkül.Ha készitet valaki ilyet,akkor megkérném segitsen.Előre is köszönöm.
