PCIe-6323 cards have a setoff when measuring analog input voltage

[cjr189]

I used a function generater to input a 1V sine wave(setoff 0) into ai0 of BNC-2110 switching to the ground, but the test panel displayed a sine wave ranging from 4-6V.

And the setoff may vary with time, sometimes it can be 5V. Is there any way to avoid it?

Hi cjr189:

Try changing the terminal configuration, I have seen this issue before and it was caused by a wrong setting of the terminal configuration. 

For instance refer to this Knowledge Base article, even though it makes reference for USB devices, this might as well happen in other devices.
