Section 4 Calibration

Calibration Overview

When a DVC6200p 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 perform Device Setup to configure and calibrate the
instrument. Calibration of the pressure sensors generally is unnecessary; however if pressure sensor calibration is
required follow the appropriate procedure below.
For detailed calibration information, refer to the following calibration procedures.

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.
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.
D Manual Calibration —This procedure permits manual calibration of the travel. This calibration procedure allows you
to determine the 0% and 100% calibration points.
D Relay —This procedure permits adjustment of the pneumatic relay.
If a double‐acting relay is used, you will be prompted to run the relay adjustment when auto or manual calibration is
selected. Select Yes to adjust the relay, select No to proceed with calibration. For additional information, refer to Relay
Adjustment in this section.
Note
Relay Adjustment is only available for the double‐acting relay (Relay A).
D Pressure A— This procedure permits calibrating the pressure A sensor. Normally the sensor is calibrated at the
factory and should not need calibration.
D Pressure B —This procedure permits calibrating the pressure B sensor. Normally the sensor is calibrated at the
factory and should not need calibration.
D Supply Pressure —This procedure permits calibrating the supply pressure sensor. Normally the sensor is calibrated at
the factory and should not need calibration.
Auto Calibration
Select Auto Calibration on the Travel tab from the Configure > Calibrate menu.
