The NI Built-in Simulated Handler Driver launches the Start of Test dialog box during the StartOfTest entry point when you enable the Show Handler Dialogs option on the Configure Built-in Simulated Handler Driver dialog box and you use the Batch or Sequential process model. The Start of Test dialog box displays information about the number of DUTs tested, the number of DUTs left to test, and the active sites.

When using the Batch process model, use the checkboxes to enable or disable sites. Enable the Do not show this dialog again for this lot option to hide the dialog box for the remainder of lot testing.
