problem of measurement with the ad7714

Hello,

My ad7714 gives me some trouble.

I want to measure the current of a rheostat through a shunt resistor.

It works if the current doesn't change. However if the current changes the measures made by the converter are false.

This screenshot show a measure of the current. We can see that there is an increase of the current while the real current decrease.

Can you help me?

 

PS : Sorry for my mistake, I'm french.
