Neurons Analog Input (AI) measurement accuracy problem

[wizro_pl]

After installation brand new Neuron in group 1 on Analog input 1_01 shows the value 0.017V (when it is connected to the GND)
According to data sheet point 4.3 measurement accuracy should be +/-0.5% it means maximum deviation for 1V on AI should be 0.005V.

How can I tune Neurons analog input to get 0V?

@wizro_pl That is a common behaviour of most analogue inputs... If you want to have 0 than set a limit eg 0.03V that everything below is 0V
