For more information on system “permissives” please see row 24 of the sheet “T. S.” worksheet, accessible by pressing the “Technical Support” button on most pages in the demonstrator file. Test for Stability of Operations Before Making Suggestions: The system will not make recommendations unless it has determined operations to be at steady-state when prior compositions/temperatures are compared to current (N/A if using lab data). When instability is detected a warning is activated. The engineer can set the limits on this t
