Thank you, but as I already wrote:

calibration after warming up, helps before rebooting. Then again ...

Please contact your seller to return factory for repair

Sir, you can try to replace the D102 (AD8370AREZ).

Replaced part D102 (AD8370AREZ) - did not help. Any more ideas?

That should be all right.
First power on, and wait for 30 minutes to do self calibration.
Turn on again and wait for half an hour. Zero-level offset will decrease.
The performance of individual components is affected by temperature. Wait until the temperature inside the machine is stable, then use it again.

OK.
All this, of course, is good, but why in the second channel this problem does not exist to such ...

Sir, it could be that there's a resistance or a capacitor broken. It can't be judged accurately.

Sorry, we can't make a correct judgement.
