Display and Configuration
Integral Display The optional integral LCD can display discrete state and diagnostic information. Display updates at each
wireless update
Remote Display Data can be read remotely by using the four-digit Rosemount 751 Field Signal Indicator. For further
information, see the Rosemount 751 Product Data Sheet (Document Number 00813-0100-4378)
Configuration Tools
(See earlier “Output” diagrams)
Emerson Field Communicator (e.g. 375/475 Field Communicator),
Radar Configuration Tools (RCT) software package for PC (included with delivery of transmitter), or
Emerson AMS™ Device Manager for PC (visit www.emersonprocess.com/AMS for further information), or
or DeltaV or any other DD (Device Description) compatible host systems
Notes:
• DTM (compliant with version 1.2 of the FDT/DTM specification) is also available supporting
configuration in for instance Yokogawa Fieldmate/PRM, E+H™ FieldCare, and PactWare™
• To communicate using RCT or AMS Device Manager, a HART modem is required. The HART modem is
available as an RS232 or USB version (see “Accessories Rosemount 3308” on page A-20)
• The transmitter can be pre-configured by selecting Options code C1 (page page A-18) and sending a
completed Configuration Data Sheet (CDS). The CDS is available from www.rosemount.com

Temperature Limits
Ambient Temperature The maximum and minimum ambient temperature for the electronics depends on the process temperature
and on the approval (see “Product Certifications” on page B-1).
• The temperature range for the optional Integral Display is –40 °F (–40 °C) to 185 °F (85 °C)
• To lower the temperature around the electronics, a Remote Mounting Connection can be used. The
maximum temperature for the Remote Housing Connection at the vessel connection point is
302
° F (150 ° C).
Temperature Limits Verify that the operating atmosphere of the transmitter is consistent with the appropriate hazardous
locations certifications.
