5.3.6 Saturation properties

The saturation properties for all 35 refrigerants can be displayed.
The temperatures are displayed constantly for single-component
and azeotropic refrigerants. The display for non-azeotropic
mixtures is made as in the pressure gauge screen:
blue: after complete evaporation
red: after complete condensation

5.3.7 Pressure type

The absolute pressure is normally measured. If you wish to have
the same display as conventional manifolds,
for the quasi-relative display mode. In this case, 1,013 mbar is
subtracted from the measured value.
