6. Calibration
6.1. Recommendations for Transmitter Calibration
The STT750 SmartLine Temperature Transmitter does not require periodic calibration to maintain
accuracy. Typically, calibration of a process-connected Transmitter will degrade, rather than augment
the capability of a smart Transmitter. For this reason, it is recommended that a Transmitter be
removed from service before calibration. Moreover, calibration must be accomplished in a controlled,
laboratory-type environment, using certified precision equipment.
6.2. Calibration Procedures
For a Transmitter operating in analog mode, you must calibrate its output signal measurement range
using any compatible hand-held communicator or a local display.
One calibration option is to use the Honeywell MC Toolkit (MCT). Refer to the MC Toolkit
(MCT202) User Manual, # 34-ST-25-20 or (MCT404) User Manual, Document # 34-ST-25-50.
Calibration information and procedures for a Transmitter operating in the HART mode are provided
in the STT750 Series HART Option User’s manual, document number 34-TT-25-15, Section on
“Calibration.”
