I am using logo with load cell and a/d amplifier, after calibrating the load cell and testing the program the analog reading never give zero reading but always gives me 0.05 or 0.1. I checked the reading with a multi meter and it was around 1mv.

so is there any way to make the logo neglect such small voltages??

 The analog MUX works well.

Thanks very much.
