Numeric View of Data and Control Variables 
As you familiarize yourself with CIRAS-3 you will begin to establish your own preferences of how and 
what you would like to see on the console for differing circumstances of data collection and various 
applications.  Numeric View, as its name implies, provides an overview in numeric form of what is being 
measured, calculated and controlled at any point in your CIRAS-3 session.  The categorized information 
is clearly placed in groupings on the screen: Measured Data, Photosynthesis Data, Fluorescence Data 
and Environmental Controls.
