The indication Practical tip using the example of the "connection of a pressure transmitter 1 .. 7 bar":
on the pressure transmitter here (> -1 bar) is obviously relative to the ambient pressure. The
adjustment of the pressure transmitter in the controller is performed using absolute pressure values
(the absolute pressure cannot be negative). In order to parametrise the above pressure transmitter
with the relative pressure indication -1 bar (at 4 mA or 0 V) and 7 bar ( at 20 mA or 10 V), the
ambient pressure (1 bar) must be added. The input in this example is as follows: 0..8 bar.
