Engineering units
The unit is capable to operate each individual application using different engineering units. The
engineering units for each application are set up in the sub menu Setup (all parameters) Æ
Application Æ Application ... Æ Eng. units. The following set-up is possible:
!
Note!
The selection of the engineering units for the flow (volume), pressure and temperature is done in
the set-up for each individual sensor.
A definition of the important system engineering units can be found in Chapter 11 "Appendix" of
these operating instructions.
