The SO
background is the amount of signal read by the analyzer while

sampling zero air.
The Adjust Background screen is used to perform a manual zero
background calibration of the instrument. As such, the instrument should
sample zero air until stable readings are obtained. The button labeled
Adjust Background allows the user to change zero background. The second
button called Adjusted Concentration shows what the new SO
concentration would be based on the changed zero background. Press the
Calibrate button to save the adjusted zero background value.

The span coefficient is used to correct the SO
value near 1.000 with minimum/maximum limits of 0.500 and 2.000
respectively.
The user can manually change the span coefficient by entering a value in
the Adjust Span Concentration button. The second button called Adjusted
