Overview

This section contains information on commissioning and operating Rosemount

™

 3051N Smart Pressure 

Transmitters. Tasks that should be performed on the bench prior to installation are explained in this 
section.

When the HART

®

 Communicator is referenced, it refers to the 275, 375, or 475 Field Communicator as 

documented in Rosemount Report D2001019.

For your convenience, typical HART Communicator Fast Key sequences are listed for most software 
functions. These Fast Key sequences are the same for the 275, 375, and 475 Field Communicators. If you 
are unfamiliar with the communicator or how to follow Fast Key sequences, refer to 

Appendix C: HART® 

Communicator

 for communicator operations.

A typical transmitter software configuration data worksheet is provided in 

Appendix A: Specifications 

and Reference Data

.

Safety messages

Procedures and instructions in this section may require special precautions to ensure the safety of the 
personnel performing the operations. Information that raises potential safety issues is indicated by a 
warning symbol ( ). Refer to the following safety messages before performing an operation preceded 
by this symbol.

Explosions can result in death or serious injury.

Do not remove the transmitter covers in explosive environments when the circuit is alive.

Electrical shock can result in death or serious injury.

Avoid contact with the leads and terminals. High voltage that may be present on leads can cause 
electrical shock.
