4.5.5 Pressure change (slope), rising
Calculates the pressure change in % / minute
(P1 - P0) / t
P0
=
Initial pressure
P1
=
Pressure recorded by Measuring interval t
t
=
adjusted Measuring in minutes
Example: Pressure rises from 3 to 5 bar based on a measuring interval of 5 minutes: → (5 - 3) / 5 = 0,4 bar / minute
