Praxis tip using the example of the ”connection of a pressure transmitter - 1 .. 7 bar”:

Here the indication on the pressure transmitter is clear (-> -1 bar) relative to the ambient pressure The 
adjustment of the pressure transmitter in the controller is carried out using absolute pressure values 
(the absolute pressure cannot be negative). In order to parameterise the above pressure transmitter 
with the relative pressure indication - 1 bar (at 4 mA, i.e. 0 V) at 7 bar ( at 20mA, i.e. 10 V) the ambient 

pressure (1 bar) must be added. 

The entry is carried out as follows: 0..8 bar.
