We tested this particular card using external resistance standards and it failed multiple ranges. These same failures were verified by another outside organization. We sent the card to NI for alignment and their as-found data indicates the resistance is good (but AC V is out of tolerance). Putting the card back into the original chassis, we get a resistance failure. When we swapped to another local chassis, the resistance works great.
We're new to using PXI cards. Does anyone have any explanations/recommendations? Appreciate the assist!
