Background Gas
This selection allows for the proper background gas to be set. It is critical that
the background is chosen to represent the actual process gas as closely as pos-
sible, The background gas is typically chosen at the factory during calibration
to ensure the best accuracy, based on the customer application data. However, it
may be changed using this utility. Changing the background gas results in the ap-
plication of a multiplication factor to the factory calibration curve
