  3. Weir DMA run interface • Interface appears when called • Program supplied call and optional data file, model, type of analysis and Weir DMA Macro to use • Analysis run independent of the user • Program will time out if data is not available of if it is held-up by the user. • Program restarts on next DMA call Weir DM/DMA

  4. Weir DMA Macro Setup Interface Screens

  5. Source • Specifying the source location of the data for the Macro Weir DM/DMA

  6. Process Window Setup 2 • Variables to analyze and their target PW ranges Weir DM/DMA
