The user sets the span concentration by pressing the Edit Span 
Concentration button. The Calculated Low Range NO Span 
Coefficient button will show what the span coefficient will be set to if 
the Calibrate button is pressed.

Enter the NO calibration gas concentration using the pushbuttons, and 
then press 

Calibrate
