1 Display of gas name and equivalence factor
2 Favorites button for fast configuration of "gas equivalent selection" after set
up, see "Touch screen settings [}17]", ”Assigning favorite buttons”.
You have a choice of two methods:
• To conveniently set the correction factor, use the "Gas equivalent selection
[}27]". There, the correction factor can be selected from a self-defined list, see
"Configure gas list [}28]", or switched back to the tracer gas.
• Alternatively, it is possible to calculate and configure the correction factor. For
information on calculation, see "Calculate equivalence factor [}29]". For
information on configuring the device, see "Set equivalence factor and molar mass
[}30]".
