Section 5 Calibration

Calibration Overview

When a DVC6200f 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 pressure sensors generally is unnecessary.
However, after mounting on an actuator, perform the initial setup then calibrate travel by selecting Configure / Setup >
Calibration > Auto Calibration. For more detailed calibration information, refer to the following calibration procedures.

Calibration

Field Communicator TB > Configure/Setup > Calibration
D Auto Calibration —This procedure automatically calibrates the travel. The calibration procedure uses the valve and
actuator stops as the 0% and 100% calibration points. See page 214.
D Manual Calibration —This procedure permits manual calibration of the travel. This calibration procedure allows you
to determine the 0% and 100% calibration points. See page 214.
D Relay —This procedure permits adjustment of the pneumatic relay. See page 215.
D Supply Pressure —This procedure permits calibrating the supply pressure sensor. Normally the sensor is calibrated at
the factory and should not need calibration. See page 216.
D Pressure A— This procedure permits calibrating the pressure A sensor. Normally the sensor is calibrated at the
factory and should not need calibration. See page 217.
D Pressure B —This procedure permits calibrating the pressure B sensor. Normally the sensor is calibrated at the
factory and should not need calibration. See page 217.
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.
