(I.S.) installations. Refer to the 2051 reference manual (document number
00809-0100-4107) for more instruction. This manual is also available electronically on
www.emersonprocess.com/rosemount.
Explosions could result in death or serious injury:
Installation of this transmitter in an explosive environment must be in accordance with the
appropriate local, national, and international standards, codes, and practices. Please review
the approvals section of the 2051 reference manual for any restrictions associated with a safe
installation.
Before connecting a HART-based communicator in an explosive atmosphere, make sure
the instruments in the loop are installed in accordance with intrinsically safe or
non-incendive field wiring practices.
In an Explosion-proof/Flameproof installation, do not remove the transmitter covers when
power is applied to the unit.
Process leaks may cause harm or result in death.
To avoid process leaks, only use the o-ring designed to seal with the corresponding flange
adapter.
Electrical shock can result in death or serious injury.
Avoid contact with the leads and the terminals. High voltage that may be present on leads
can cause electrical shock.
Conduit/Cable Entries
Unless marked, the conduit/cable entries in the transmitter housing use a 1/2-14 NPT
thread form. Only use plugs, adapters, glands or conduit with a compatible thread form
when closing these entries.

transmitter.
- Default security is off ( ).
Use the following procedure to change the switch configuration:
1. If the transmitter is installed, secure the loop, and remove power.
2. Remove the housing cover opposite the field terminal side. Do not remove the
instrument cover in explosive atmospheres when the circuit is live.
3. Slide the security and alarm switches into the preferred position using a small
screwdriver.
4. Reattach the transmitter cover. The cover must be fully engaged to comply
with explosion-proof requirements.
1. Loosen the housing rotation set screw.
2. First rotate the housing clockwise to the desired
location. If the desired location cannot be
achieved due to thread limit, rotate the housing
counter clockwise to the desired location (up to
360° from thread limit).
3. Re-tighten the housing rotation set screw.

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.

Quick Start Guide
1. 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 in H2O = + 7.5 inH2O (compared to
factory settings) values outside this range will be rejected by the
transmitter.
Trimming with a Field Communicator
1. Connect the Field Communicator, see “Connect the wiring and power up” on
page 9 for instructions.
2. Follow the HART menu to perform the desired zero trim.
Table 5. Zero Trim Fast Keys
Trimming With Configuration Buttons
A zero trim is to be performed using one of the three possible sets of external
configuration buttons located under the top tag.
To access the configuration buttons, loosen the screw and slide the tag on the top
of the transmitter. Confirm the functionality using Figure 12.
