Span Coefficient.
The user sets the span concentration by pressing the Edit Span
Concentration button. The New Span Coefficient button will show
what the span coefficient will be set to if the Calibrate button is
pressed.
3. Enter the NO calibration gas concentration using the pushbuttons, and
then press Calibrate to calculate and save the new high range NO span
coefficient based on the entered span coefficient.
