Hey. Today I got a Hameg HM 312. I am completely new to analog Oscilloscopes but well we are on lockdown. It seems to work. At least it is showing the proper waveshapes. But it is not possible to get the signal to 0V in the y axis. I read it has something to the with the y amplifier. Can somebody help maybe?

thanks in advance and regards
Chris

So. I cleaned it. It was surprisingly clean considering the age. Unfortunately I still cannot move the line up. It’s not even within the printed grid of the screen. It’s at the bottom of the frame. Is this a common problem?
Have a great Sunday. //ChrisD9A0C872-675C-4CE9-8DF7-AAF966FF1306.jpeg
