6.2.6 Parameter/Area
Some calculated variables relate to particular reference values (ambient
conditions or factors for certain probes). These can be entered by means of
calculation parameters.
Parameters used for calculating variables:
Parameters Calculated measuring variables
Temp. (reference temperature) Flow velocity, volumetric flow rate (for measurement with a
(435-3/-4 only) pitot tube)
Humid. (reference humidity) Flow velocity, volumetric flow rate (for measurement with a
(435-3/-4 only) pitot tube)
Pres. (reference pressure) Flow velocity, volumetric flow rate (for measurement with a
pitot tube or hot wire probe), heating/cooling performance (enthalpy)
Area (cross-section area) Volumetric flow rate
P-factor (pitot tube factor) Flow velocity and volumetric flow rate (for measurement with a
(435-3/-4 only) pitot tube)
abs alt. Barometric air pressure
