Note
Transmitter output is not safety-rated during the following: configuration changes,
multidrop, and loop test. Use alternative means to ensure process safety during
transmitter configuration and maintenance activities.
7.3.1 Damping
User-selected damping affects the transmitter's ability to respond to changes in the
applied process. The damping value + response time must not exceed the loop
requirements.
