10.6.2 Performing external compensation
The External compensation submenu contains parameters which can be used to enter
external or fixed values. These values are used for internal calculations.
The Fixed process pressure parameter is set to the value 0 bar abs. (ex works). In
this case, the measuring device ignores the pressure read in via PROFIBUS PA. For the
measuring device to use the external (read-in) pressure, a value > 0 bar abs. must be
entered in the Fixed process pressure parameter.
