6.1 Overview
The STT700 SmartLine Temperature Transmitter does not require periodic calibration to maintain
accuracy. Typically, calibration of a process-connected transmitter may degrade, rather than augment
its capability. For this reason, it is recommended that the transmitter be removed from service before
calibration. Moreover, calibration should be accomplished in a controlled, laboratory-type
environment, using certified precision equipment.
6.2 Calibration Recommendations
If the transmitter is digitally integrated with a Honeywell control system, like the Total Plant Solution
(TPS) or Experion PKS system, you can initiate range calibration and associated reset functions
through displays at the Universal Station, Global User Station (GUS), or Experion Station. However, a
range calibration using the MC Toolkit with the transmitter removed from service is recommended.
Calibration with the transmitter removed from service needs to be accomplished in a controlled
environment. Details for performing a calibration reset through the Universal Station are provided in
the PM/APM SmartLine Transmitter Integration Manual, PM12-410, which is part of the TDC 3000
system book set.
6.3 Test Equipment Required for Calibration
Depending upon the type of calibration you choose, you may need any of the following test equipment
to accurately calibrate the transmitter:
Digital voltmeter or millimeter with 0.01% accuracy or better
Honeywell MC Toolkit: Use the MC Toolkit application to calibrate the STT700 DE model
and the FDC application to calibrate the STT700 HART model.
Calibration-standard input source with a 0.01% accuracy
250 ohm resistor with 0.01% tolerance or better.
