Requirement for shield and grounding
The pressure transmitter must be grounded via the process connection.
When working during a running process operation, measures to prevent electrostatic discharge on the connection
terminals should be taken, as a discharge could lead to temporary corruption of the measured value.

5.4 Functional check
The output signal must be proportional to the prevailing pressure. If this is not the case, this may indicate a damaged
diaphragm of the process connection. In this case, see chapter 6 "Errores".
