Sziasztok!
A címben említett " gyönyörűség" mutatója bekapcsolás után (1x 6F22+1xR14 elem)önálló életre kel,
föl-alá kuszik, nyugtalan :-) Duál-FET szivárgásra tippelek de elképzelésem sincs, hogy mivel
tudnám helyettesíteni a hibaforrás kizárása céljából. A FET azonosítója: IS001 410 Sharp
(FET cserével "MEGOLDVA")
Segítségeteket előre is köszönöm.
Üdvözletem
Hello,
I purchased a Hameg 404-2. It works normally as an analog scope. But what doesn't work is the readout, the display of the numbers and letters on the screen. These are pixelated. I have restored several vintage scopes (Hameg, Tektronix, Leader) but have no experience with this type of scope. Where can I suspect the error, which module is in question? What is the procedure? There is a circuit diagram, but it doesn't really help me. I checked the supply voltages and everything was spot on. Can someone help me? Thank you.

Can anyone share an user manual this one ? Please help me . Thank you so much
Sziasztok!A mellékelt MOSFET teszterrel bemérhető az IGBT?A kapcsolást egy kedves kollégánk rajza alapján mellékelem.A készüléket megépítettem.A gyakorlatban jól vizsgázott.Egy mosógép panel javításánál a táp.-ban lévő MOSFET bemérhető volt vele.A MOSFET zárlatos volt.Kicseréltem.A mosógép "meggyógyult."Másik kérdésem,az,hogy,ha mérhető vele,akkor a NYÁK-ba beforrasztott alkatrész is mérhető-e vele?Az emlegetett MOSFET ki volt forrasztva a NYÁK-ból amikor bemértem.Most megpróbáltam a GB6B60KD-t (NYÁK-ba forrasztva)megmérni vele.Ez egy mosógép panelben van.A hajtás háromfázisú.A villanymotor tekercsei deltába vannak kötve.A GB6B60KD vizsgálatánál,a teszter bekapcsolása után, a bekapcsolt állapotot jelző LED világított,majd fokozatosan csökkenő fénnyel kialudt.A bekapcsolás sem,sikerült,a kikapcsolás sem,sikerült.Vajon nem jó erre a célra a műszer?Vagy áramkörön belül nem használható?Nem szívesen forrasztanám ki az alkatrészeket,mert egy jó panelt mérek.A műszert szeretném,erre a célra kipróbálni!Vagy vegyek a "bótba" egy "Isten bizony jó" IGBT-t és azzal kísérletezzek?
