Voltage measures with usb-6210

[Saiko]

Hi,

I'm trying to carry out three parallel voltage measures with a USB-6210 Card. Whatever the control software I'm using (vi under LabVIEW + DAQ, SignalExpress or Measurement and Automation Explorer), I get the same strange signal. In attachment please find an example from the control panel. As I'm a beginner with LabVIEW, I suspect some stupid mistake, but I checked my wiring and drivers without finding problems.  

Thanks for your help  

Best regards,

Saiko

Hello Saiko,

Thank you for posting on National Instruments' forum.

This link (french post) will resolve your problem : here.

The problem was using a Differential mode (AI- AI+) to acquire an analog signal instead of RSE (AI GND).
