Thank you, but as I already wrote:

After self-calibration or an hour-long warm-up, everything is fine, but it disappears if the oscilloscope is reset.

calibration after warming up, helps before rebooting. Then again, half an hour or an hour you need to wait until the mark is aligned with the signal. It seems that the thermal compensation of channel 1 is not working well.

half an hour after starting up, and then make it self-correcting, hope that can be helpful.
