Hello,

I have attached four images to this post to clarify the problem.
Please consider the image captions.

When trying to calibrate the oscilloscope, the calibration process does not make any progress. It stays like it is shown in the image.

Readings have a big voltage offset. I cannot meassure the square wave generator properly, because of voltage offset and the scaling is also wrong.

Thank you in advance for your effort.

Kind regards,
Mika
