2. From the adjustment menu, select the direction and size of change required to set the travel at 0%.
Selecting large, medium, and small adjustments causes changes of approximately 10.0%, 1.0%, and 0.1%, respectively.
If another adjustment is required, repeat step 2. Otherwise, select Done and go to step 3.
3. From the adjustment menu, select the direction and size of change required to set the travel to 100%.
If another adjustment is required, repeat step 3. Otherwise, select Done and go to step 4.
4. From the adjustment menu, select the direction and size of change required to set the travel at 0%.
If another adjustment is required, repeat step 4. Otherwise, select Done and go to step 5.
5. From the adjustment menu, select the direction and size of change required to set the travel to 100%.
If another adjustment is required, repeat step 5. Otherwise, select Done and go to step 6.
6. From the adjustment menu, select the direction and size of change required to set the travel to 5%.
If another adjustment is required, repeat step 6. Otherwise, select Done and go to step 7.
7. From the adjustment menu, select the direction and size of change required to set the travel to 95%.
If another adjustment is required, repeat step 7. Otherwise, select Done and go to step 8.
8. Place the instrument In Service and verify that the travel properly tracks the current source.
Calibration using the Aux Terminal Connections
Note
Pressure range is not captured during this procedure.
Travel calibration can also be accomplished by shorting the auxiliary terminal connections for 3 to 5 seconds. You can
abort the procedure by shorting the auxiliary terminals for 1 second.
To enable this calibration Auxiliary Terminal Action must be set to Auto Calibration. The instrument Operational Status
during calibration is Calibration in Progress.
Use this calibration procedure to calibrate the digital valve controller travel whenever the I/P converter or relay is
replaced. Do not use this calibration for initial calibration when mounting the instrument on an actuator, or if the
printed wiring board assembly was replaced.
You can use the auxiliary terminal connections to calibrate the digital valve controller if you suspect calibration has
changed due to drift. However, prior to initiating calibration for this reason, perform a Valve Signature diagnostic test,
using ValveLink software. This will capture the as‐found data for future root cause analysis.

Pressure Sensors
Note
The pressure sensor is calibrated at the factory and should not require calibration.
