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,
Rafael Leite

My setup is CSR. I connected the battery pins AIGND 67 (-) and 68-CH0 (+) and also in other channels.

Hi Rafael,
The best connection approach using a battery is RSE or just single-ended. You can find details here:

Test the board using MAX with a known source of signal, if using DAQmx driver execute self-test and self-calibrate.
Make sure that any software change was made in this machine, and if was tell us what changed.
If you have any doubt feel free to contact us,
Regards,
