6.5 Commissioning
The software operating data of the transmitter must be set to meet the requirements
of the current measuring job and must correspond to specifications on the software
rating plate. If the software operating data do not match the data on the software
rating plate, the rating plate must be corrected or replaced by a new one (Chapter
3.5.2, page 92).
The hardware operating data must also match the data on the hardware rating plate.
If changes are made to the hardware parameterization (switching over from current
to voltage or vice versa), the current state on the hardware rating plate must be
documented (see Chapter 3.5.3, page 92).
