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

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.

Quick Start Guide
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
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).
and the Field Communicator Reference
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.
