Diagnostic Test Tools - eBIRST and BIRST Information

    Our Diagnostic Test Tools, BIRST - Built-in Relay Self-Test and eBIRST Switching System Test Tools allow users to find faults in switching systems easily. Below there is a selection of topics on the two sets of tools. We are committed to supporting both types of tools, new matrices will be supported by the embedded BIRST where it makes sense while most switching systems will be supported by eBIRST.
