To test relays with the NI Switch Health Center, complete the following steps:

  1. Disconnect any cables or interchangeable test interfaces (ITAs) from the device(s).

    Note Note  Safety interlock circuitry on the NI SwitchBlock relay cards prevents the relay test from running until all external connections have been disconnected.
  2. Launch the NI Switch Health Center from either MAX or the Start menu.

    From MAX

    Complete one of the following:

    • Right-click on a resource and select NI Switch Health Center
    • Select a resource and click NI Switch Health Center in the task bar.

    The NI Switch Health Center launches, initializes, and begins testing relays in the selected resource.

    From the Start Menu

    1. If you have only one resource present, the relay test starts automatically. If you have more than one resource installed, select the resource you want to test in the listbox from the NI Switch Health Center - Setup dialog box that displays.
    2. Click the Start button.

      The NI Switch Health Center initializes and begins testing relays in the selected resource.

  3. The relay test displays the following information:
    • Relay functionality using the integrated relay continuity test
    • Relay contact resistance changes using the integrated relay resistance test
    • Relay cycle counts using relay count tracking
    Note Note  Some devices may not support the integrated relay resistance test.

    Click Abort at any time to stop the test and release the resource for use.

  4. Click the Start button to repeat tests as necessary.

After completion of each relay test, you can generate a report documenting the results of the test.
