Thank you for your patience. I will try this.

and I will report the result

Hello.
I applied what you said.
However, the shift continues,
I think I made the other settings correctly. Because I applied the code in the link I gave one to one.
I had a new integrated: FDC1004.
I also tested it. But its values are shifting too. :(
I have also tried other integration that I have run with your help before (FDC2114).
But its values are shifting too. :(
So this problem stems from a different place.
Maybe that is why wet washing the circuits may be a problem. How can I solve this?
Do you have any other suggestions?

No.
The issue is that you are not configuring the baseline filter values.
These are registers 0x2B to 0x40.
The setting for the ELEPROX baseline, is separate to the ones for the
other twelve readings. The example code you have used, is not setting
up the ELEPROX baseline filter. Hence it won't adjust....
These are the registers starting at MHDPROXR. Note nothing put into
these in the settings you are using.
Look at the document I pointed to earlier about how to setup these
values. You could start by just trying the values used for the other
channels.

Yeah. The parts you acquire are not configured. But this does not explain why other sensors shift value. I work for the right configuration, I will return to you.
