Problem with my PCI-6023e

Hi!

There is a PCI-6023e National Instruments in my system but the analog inputs are in high positive or negative level. I verified the control panel and Max instalation It was ok.
I installed a battery of 1,5Vdc on the analog inputs to verify voltage measurement but the measurement remained saturated with 10 Vdc in all channels.

Thanks,
