6.11 Procedure to Reset Calibration
A STT700 SmartLine HART Temperature Transmitter can have its incorrect calibration data erased by
resetting the device back to default values using the MC Toolkit. The default values return the
transmitter calibration to the original factory
characterization
values. However, note that this is not
the
final factory calibration
, which is performed per the ordered range.
Incorrect or inaccurate user calibrations may be reset by performing a Reset Correct operation. This
calibration reset will return the device to
original factory calibration accuracy
. Factory calibration is
extremely accurate and user calibration is not typically recommended. However, if user calibration to
a customized range is desired, it is recommended that the input calibration procedures be performed
again after the calibration reset.
