Issue Details

I think my CMOS battery has failed in my PXI or PXIe controller because the controller's clock repeatedly loses its time. What type of batteries are used in these controllers and how can I replace them?


Note:National Instruments is not liable for damage incurred while changing a CMOS battery.  Recommended procedure is to send your controller in to Return Material Authorization (RMA) to have the battery replaced; however, the 3 Volt battery can be replaced by an end user if desired.
