3. When the responses stabilize, from the Home screen, choose
Calibration>Calibrate Span Coefficients>Calibrate Low Range NO
Span Coefficient.
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.
4. Enter the NO calibration gas concentration using the pushbuttons, and
then press Calibrate to calculate and save the new low range NO span
coefficient based on the entered span coefficient.
