Setup → Medium selection
1. Call up the Medium selection wizard.
2. In the Select medium parameter (→  80), select the Gas option.
3. In the Select gas type parameter (→  80), select the Air option.
 The density is determined according to NEL 40.
4. Enter the value in the Relative humidity parameter (→  81).
 The relative humidity is entered as a %. The relative humidity is converted
internally to absolute humidity and is then factored into the density calculation
according to NEL 40.
5. In the Fixed process pressure parameter (→  82), enter the value of the process
pressure present.

Setup → Advanced setup → Medium properties
6. Call up the Medium properties submenu.
7. In the Reference pressure parameter (→  99) enter the reference pressure for
calculating the reference density.
 Pressure that is used as a static reference for combustion. This makes it possible
to compare combustion processes at different pressures.
8. In the Reference temperature parameter (→  99) enter the temperate for
calculating the reference density.
Endress+Hauser recommends the use of active pressure compensation. This fully rules
out the risk of measured errors due to pressure variations and incorrect entries .
