Pressure compensation
The pressure is used for pressure compensation of the DRYCAP

sensor in order to ensure the best possible measurement accuracy. If
the process pressure differs from normal ambient pressure, the value
has to be entered in the transmitter memory. The pressure also has a
considerable effect on the ppm
v
value. The pressure to be entered is
the absolute pressure in hPa (for converting pressure units, see
Appendix 8).
• Select Pres in the main menu and the following appears:
• Pressing ENT returns the programme to the main menu without
