Quick Start Guide
NOTICE
This guide provides basic guidelines for the Rosemount 644. It does not provide instructions for detailed
configuration, diagnostics, maintenance, service, troubleshooting, or installation. Refer to the Rosemount
644 Reference Manual for more instruction. The manual and this guide are also available electronically on
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. Review the Product Certifications for any
restrictions associated with a safe installation. In an Explosionproof/Flameproof installation, do not remove
the transmitter covers when power is applied to the unit.
Process leaks may cause harm or result in death.
Install and tighten thermowells or sensors before applying pressure.
Do not remove the thermowell while in operation.
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.

1.0 Configure (bench calibration)
The Rosemount 644 communicates using the Field Communicator
(communication requires a loop resistance between 250 and 1100 ohms. Do not
operate when power is below 12 Vdc at the transmitter terminal). Refer to the
Rosemount 644 Reference Manual and the Field Communicator Reference
Manual for more information.
1.1 Update the Field Communicator software
The Field Communicator field device revision Dev v6, Device Dashboard (DD) v1
or higher is required for complete functionality. The device will communicate
with all previous Rosemount 644 DD revisions.
Perform the following steps to determine if an upgrade is required.
1. Connect the sensor (see wiring diagram on the inside of housing cover).
2. Connect the bench power supply to the power terminals (“+” or “–”).
3. Connect a Field Communicator to the loop across a loop resistor or at the
power/signal terminals on the transmitter.
4. The following message will appear if the communicator has a previous version
of the device descriptors (DDs).
Upgrade the communicator software to access new XMTR functions. Continue with
old description?
Note
If this notice does not appear, the latest DD is installed. If the latest version is not available,
the communicator will communicate properly. Note that, when the transmitter is
configured to utilize the advanced features of the transmitter (i.e. one of the added sensor
input types), the user will experience trouble communicating and will be prompted to turn
the communicator off. To prevent this from happening, upgrade to the latest DD or answer
NO to the question and default to the generic transmitter functionality.

5.0 Wire and apply power
5.1 Wire the transmitter
Wiring diagrams are located inside the terminal block cover.
Figure 4. Sensor Connections Diagram
5.2 Power the transmitter
1. An external power supply is required to operate the transmitter.
2. Remove the terminal block cover (if applicable).
3. Connect the positive power lead to the “+” terminal. Connect the negative
power lead to the “–” terminal.
4. Tighten the terminal screws. When tightening the sensor and power wires, the
max torque is 6 in-lbs (0.7 N-m).
5. Reattach and tighten the cover (if applicable).
6. Apply power (12–42 Vdc).
5.3 Load limitation
The power required across the transmitter power terminals is 12 to 42.4 Vdc (the
power terminals are rated to 42.4 Vdc). To prevent damaging the transmitter, do
not allow terminal voltage to drop below 12.0 Vdc when changing the
configuration parameters.
1. The transmitters must be configured for at least a 3-wire RTD in order to recognize an RTD with a
compensation loop.
2. Rosemount Inc. provides 4-wire sensors for all single element RTDs. Use these RTDs in 3-wire
configurations by leaving the unneeded leads disconnected and insulated with electrical tape.

6.0 Perform a loop test
The loop test command verifies transmitter output, loop integrity, and operation
of any recorders or similar devices installed in the loop.
6.1 Traditional interface
1. Connect an external ampere meter in series with the transmitter loop (so the
power to the transmitter goes through the meter at some point in the loop.)
2. From the Home screen, select 644H and 644R: 1 Device Setup, 2 Diag/Serv,
1 Test Device, 1 Loop Test.
3. Select a discrete milliampere level for the transmitter to output.
a. At Choose Analog Output, select 1 4mA, 2 20mA
OR
b. Select 3 Other to manually input a value between 4 and 20 milliamperes.
4. Select Enter to show the fixed output.
5. Select OK.
6. In the test loop, verify the transmitter’s actual mA output and the HART®mA
reading are the same value. If the readings do not match, either the
transmitter requires an output trim or the current meter is malfunctioning.
7. After completing the test, the display returns to the loop test screen and
allows the user to select another output value. To end the loop test, select
5 End and Enter.
6.2 Device dashboard

1 Loop Test.
3. Select a discrete milliampere level for the transmitter to output.
a. At Choose Analog Output select 1 4mA, 2 20mA
OR
b. Select 3 Other to manually input a value between 4 and 20 milliamperes.
4. Select Enter to show the fixed output.
5. Select OK.
6. In the test loop, verify the transmitter’s actual mA output and the HART mA
reading are the same value. If the readings do not match, either the
transmitter requires an output trim or the current meter is malfunctioning.
