The NO background is the amount of signal read by the analyzer in the
x
NO channel while sampling zero air. The NO
of signal read by the analyzer in the NO
The Adjust Background screens are 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 NO channel should
be calibrated first. Both the NO and NO
operate the same way.
The button labeled Adjust NO Background allows the user to change zero
background. The second button called Adjusted NO Concentration shows
what the new NO concentration would be based on the changed zero
background. Press the Calibrate button to save the adjusted zero
background value.
