12.5.2 Adapting the diagnostic behavior
All the diagnostic messages are assigned to specific error categories at the factory. Since
other settings might be preferred depending on the application, error categories and the
effect errors have on the measuring point can be configured individually. Furthermore,
every diagnostic message can be disabled.
