An optional 3-button assembly is available to set up and make adjustments to the Transmitter. In
addition, a Honeywell Multi-Communication (MC) Toolkit (not supplied with the Transmitter) can
facilitate setup and adjustment procedures in the case of HART and DE. Certain adjustments can be
made through an Experion Station or a Universal Station if the Transmitter is digitally integrated with
Honeywell's Experion or TPS/TDC 3000 control system for HART and DE transmitters.

STT850 SmartLine Transmitter NamePlate

The Transmitter nameplate mounted on the bottom of the electronics housing (see
model number, physical configuration, electronics options, accessories, certifications, and
manufacturing specialties.
The model number format consists of a Key Number with several table selections.
Key I
STT850 - _ - _ -
You can readily identify the series and basic Transmitter type from the key number. The letter in the
third digit represents one of these basic transmitter types:

T = Temperature
For a complete selection breakdown, refer to the appropriate Specification and Model Selection
Guide provided as a separate document.

Safety Certification Information

An "approvals" nameplate is located on the bottom of the Electronics Assembly; see
exact location. The approvals nameplate contains information and service marks that disclose the
Transmitter compliance information. Refer to Appendix C of this document for safety certification
requirements and details.

Transmitter Adjustments

For HART and DE variants, Span adjustments are possible in STT850 SmartLine Temperature
Transmitters with the optional three-button assembly located at the top of the Electronic Housing (see
Figure 2).
For HART and DE you can also use the Honeywell MC Toolkit or other third-party hand-held to
make any adjustments to an STT850 SmartLine Temperature Transmitter. Alternately, certain
adjustments can be made through the Experion or Universal Station, if the Transmitter is digitally
integrated with a Honeywell Experion or TPS system. In case of Fieldbus (FF) variants, adjustments
can be made using any Fieldbus compliant DCS or Asset management system including Honeywell
Experion PKS and Honeywell FDM. Any Fieldbus compliant third party handheld configuration may
also be used.
