ä
40)
General programming rules:
• A gas group can be configured with 1 single gas or a gas mixture (max. 8 gas constituents).
• The sum of the gas mixture constituents entered must total 100.0 Mole %.
• A gas constituent and its corresponding Mole % can be entered in any order within the mixture.
• A gas constituent may have a value of 0.0 Mole % within the mixture.
• The option NOT USED is only a place holder for functions GAS TYPE 1 and GAS TYPE 2 to 8 where there is no gas
assigned. The program does not use this option for calculations.
• The option SPECIAL GAS is a substitute for other gases. The Mole % value is always 100.0%
