M series USB-6212 Output and Calibration Problems

[kylek]

Hi,

I have a NI USB-6212 DAQ and am having trouble with the output signal/voltage.  I have tried to do a self calibration but it always fails.  I ran the DAQ Diagnostic Utility and got results that agree with what I was thinking but am not sure where to go from here.  Any help would be great.  I will post my Utility results below.  When I* try to have it do the self-calibration it fails and won't continue so the results shown below are with that step skipped so that I could show the results.

Not sure where to go from here.  Any help?

I'm running into a similar issue. Ao0 is pinned at 1.5 V (unless the single point output is set to a larger value) and the self-calibration fails. Did you end up finding a solution?

Hello,

Could you create a new post for this issue? Since this is an older post it is better to make newer posts even though it is a similar issue. You'll get better help this way and more visibility.
