Calibration Overview
When a DVC6200 digital valve controller is ordered as part of a control valve assembly, the factory mounts the digital
valve controller on the actuator and connects the necessary tubing, then sets up and calibrates the controller.
For digital valve controllers that are ordered separately, recalibration of the analog input or pressure sensors generally
is unnecessary. However, after mounting on an actuator, perform the initial setup then calibrate travel by selecting
Configure > Calibrate > Travel Calibration > Auto Calibration. For more detailed calibration information, refer to the
following calibration procedures.

Field Communicator Configure > Calibrate (1‐3)
Travel Calibration
D Auto Travel Calibration —This procedure automatically calibrates the travel. The calibration procedure uses the
valve and actuator stops as the 0% and 100% calibration points.
D Manual Travel Calibration —This procedure permits manual calibration of the travel. This calibration procedure
allows you to determine the 0% and 100% calibration points.
Sensor Calibration
D Pressure Sensors—This procedure permits calibrating the three pressure sensors. Normally the sensors are
calibrated at the factory and should not need calibration.
D Analog In Calibration—This procedure permits calibrating the analog input sensor. Normally the sensor is calibrated
at the factory and should not need calibration.
Relay Adjustment—This procedure permits adjustment of the pneumatic relay.
Restore Factory Settings—This procedure permits you to restore the calibration settings back to the factory settings.
Note
The Instrument Mode must be Out Of Service and the Protection set to None before the instrument can be calibrated.
If you are operating in burst mode, we recommend that you disable burst before continuing with calibration. Once calibration is
complete, burst mode may then be turned back on.
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.
