2.5.4 Switch HART revision mode
If the HART configuration tool is not capable of communicating with
HART Revision 7, the Rosemount 3051 will load a generic menu with
limited capability. The following procedures will switch the HART
revision mode from the generic menu:
Procedure
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
Note
See Table 2-1 to change HART revision when the correct device driver
is loaded.
2.6 Step 5: Trim the transmitter
Devices are calibrated by the factory. Once installed, it is
recommended to perform a zero trim on gage 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.
Quick Start Guide July2023
16 Rosemount 3051G

For instructions using AMS Device Manager, see the Rosemount 3051
HART 7 Reference Manual.
Note
When performing a zero trim, ensure that the equalization valve is
open and all wet legs are filled to the correct level.
Procedure
Choose your trim procedure.
a) Analog Zero Trim – Sets the analog output to 4 mA.
•Also referred to as a “rerange,” it sets the Lower Range
Value (LRV) equal to the measured pressure.
•The display and digital HART output remains unchanged.
b) Digital Zero Trim – Recalibrates the sensor zero.
•The LRV is unaffected. The pressure value will be zero (on
display and HART output). 4 mA point may not be at zero.
•This requires that the factory calibrated zero pressure is
within a range of 3% of the URL [0 + 3% x URL].
Example
URV = 250 inH2O Applied Zero Pressure = + 0.03*250 inH2O = + 7.5
inH2O (compared to factory settings) values outside this range will be
rejected by the transmitter.
2.6.1 Trimming with a Field Communicator
Procedure
1. Connect the Field Communicator (see Connect the wiring and
power up for instructions).
2. Follow the HART menu to perform the desired zero trim.
