I have conected my PCI 6251 With my PC and saw that the output voltage is comming less than the desired output, (If I select 5 volt in AO, it was comming near about 1.5-2 V)
Then, I replaced the PC and I saw the output was correct.
But after few month, the PC got damaged (It is not turning on only if I conect the PCI 6251 DAQ in the PCI slot, when I remove the DAQ, it is running ok).
Then, I tried in the previous PC, and saw it is giving a correct voltage! This is really a strange matter for me!! what could be the reason?
Is it possible that the DAQ is damaged in any way?
