Operation Pressure Object
Set current atmospheric pressure to apply pressure compensation to CO
2
measurement, and to improve the calculation accuracy of pressure
dependent humidity parameters.
NOTE
Pressure and Altitude
objects are linked together. If Present Value in one
object is changed, Present Value in another object is changed
accordingly.
