No zero values


working with a new U3-HV we can't get the zero. If we connect the AIN0 to AIN3 to the ground, it shows 0; but when we disconnect to the ground, it remains at zero for few seconds, then it reads about 1.5V

The same for the the other ports, after few second they reads about 0.4V.

What's wrong?
