Hi guys,
I’m new to the EEVblog forum, but I’m watching Dave’s videos for years now.
This week someone gave me an old oscilloscope (Hameg HM412) which didn’t do anything at all.
After cleaning some of the IC pins, I got it to show a point on the screen. The point does react if you probe something, just like a normal horizontal line would. The X and Y adjust also work perfectly fine.
Another thing that I find weird is that channel 2 also has a point but it peaks in the horizontal way. Channel 1 peaks like normal: vertically. The scale of the Y axis is also messed up.
Because the point on the screen seems be the line that is cropped together, I think it could be a setting? I’m new to oscilloscopes too, but I do know quite a bit about electronics.
Do any of you know what the problem could be? Any advice is welcome!
Here is a picture with it measuring 14 VDC:
