Good evening everyone,
I’m currently busy with my electrical engineering study and around a year ago I purchased my first analog scope. The scope I have is a HM400 from Rodhe and Schwarz. When I purchased it everything was fine, but I haven’t used it for at least 6 months because it was still at my parents place. I didn’t wat to take it with me by public transport so I waited till my parent came to visit me by car and bring it along. Now I finally have it at my student home, but when I turned it on all my signals seem to be at an angle like in the picture. In the picture Chanel 1 is connected to the 10Khz probe adjust and channel 2 is not connected and configured to DC.
I did check mains ground of the socket in my room and it was connected to the mains ground in the common Living room. (Don’t know if this could the problem but I wanted to tell it just in case). I also checked the height of the screen through the ventilation holes and it is still strait, gently tapping and shaking it docent seem to have any affect as well.
Hope someone can give me a solution or any advice on this problem!
