Travel Calibration
WARNING
During calibration the valve will move full stroke. To avoid personal injury and property damage caused by the release of
pressure or process fluid, isolate the valve from the process and equalize pressure on both sides of the valve or bleed off the
process fluid.
Note
If optional limits switches are being used, power must be applied to the switch circuits throughout the automatic or manual
calibration routine. Failure to power the switches may result in incorrect switch orientation.
To manually calibrate the instrument or automatically calibrate the instrument without changing the tuning values,
the TRAVEL CALIBRATION routine is available. To access this procedure from the home screen, press the DOWN (B)
arrow key two times and then the RIGHT (") arrow key once. From there follow the prompts as illustrated in figure 18.

CALIBRATION
Note
If the valve is manually calibrated to travel less than the physical travel stops allow, manual tuning (page 22) may be required to
optimize the valve response.
Automatic calibration will provide status information as the procedure is running. Manual calibration will require you
to first adjust the input current to move the valve and then to press the RIGHT (") arrow key. After manual calibration
is complete, you will have the choice to save the calibration or exit the procedure without saving. If you exit without
saving, the last saved calibration data will be restored.
