Hello,
In order to have your message viewed by the highest number of appropriate developers, I recommend you post this question in the "Multifunction IO" category instead of the "LabVIEW General" category, since this issue is related to the use of signal conditioning hardware with a DAQ board, and not with LabVIEW programming.
Have a pleasant day.
Sincerely,
Darren Nattinger
Applications Engineer
