Integer
read/write
Use this function to configure an automatic pressure correction.
In this way, the effect of a pressure deviation between the calibration and process
pressures on the measured error for mass flow is compensated for, (see also
Operating Instructions BA107D, “Measuring accuracy” Chapter).
Options:
0 = OFF
1 = FIX (a fixed process pressure for pressure correction is specified).
Factory setting: OFF

! Note!
Function is not available unless the FIX setting was selected in the PRESSURE
MODE function (6500).
Use this function to enter the value for the process pressure which should be used
during pressure correction.
User input: 7-digit floating-point number
Factory setting: 0 bar g
! Note!
The appropriate unit is taken from the function group SYSTEM UNITS
(see Page 15).
