Pushbutton Calibration

A pushbutton near the wiring terminals in the terminal box provides a quick means to autocalibrate the instrument.
The button must be pressed for 3 to 10 seconds. Autocalibration will move the valve through the full range of travel
whether the Instrument Mode is In Service or Out of Service. However, if the Write Protection is Protected, this button
will not be active. To abort, press the button again for 1 second. The calibration button is disabled by default. To
enable it, go to Manual Setup > Instrument > Calibration Button.
Note
Pressure range (used for Pressure Fallback) is not recalibrated during this procedure.
This calibration procedure is recommended whenever the I/P converter or pneumatic relay is replaced. Do not use the
pushbutton calibration for initial calibration when mounting the instrument on an actuator, or if the printed wiring
board assembly was replaced.
If you suspect calibration has changed due to drift, first perform a Valve Signature diagnostic test using ValveLink
software to capture the as­found data for future root cause analysis.
