Looks like to be a ground loop problem.


Could you post a picture of your setup?

The gnd of the ADC converter should be at the same potential than the gnd of your pot.

Also How long are your wire. Wires could catch any electrical field around them.

Use shield cable and be sure that the gnd of your pot are directly connected to the gnd of the ADC converter


A multimeter will be a good tool to check voltage.
