If the HART configuration tool is not capable of communicating with HART

Revision 7, the 2051 will load a Generic Menu with limited capability. The

following procedures will switch the HART revision mode from the Generic Menu:

1. Manual Setup > Device Information > Identification > Message

a. To change to HART Revision 5, Enter: "HART5" in the Message field

b. To change to HART Revision 7, Enter: "HART7" in the Message field

Step 6: Trim the transmitter

Devices are calibrated by the factory. Once installed, it is recommended to

perform a zero trim on gage and differential pressure transmitters to eliminate

error due to mounting position or static pressure effects. A zero trim can be

performed using either a Field Communicator or configuration buttons.

For instructions using AMS, please see the Rosemount 2051 Product Manual

(00809-0100-4107).

Note

When performing a zero trim, ensure that the equalization valve is open and all wet legs are filled

to the correct level.

It is not recommended to zero an absolute transmitter, model 2051TA.
