Issue Details

I have a PXI Switch card. I believe that some of the relays are broken because certain channels can't connect to eachother. Is there a way to figure out exactly which relays are broken without manually checking each one of them?


The NI Switch Health Center is a product that installs with many PXI Switches. If this product is compatible with your switch card, this is a great resource for checking to see if you have broken switches. This product shows all of your relays in a graphical interface and highlights any that don't function properly.

Additional Information

Once you have identified which relays are broken, you are able to replace these relays yourself. Consult this document and the NI-Switch Help documents referred to in that document for instructions on how to do this.
