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 automatically calibrates the travel. The calibration procedure uses the valve and actuator stops as
the 0% and 100% calibration points. See page 120.
D Manual Calibration permits manual calibration of the travel. This calibration procedure allows you to determine the
0% and 100% calibration points. See page 120.
D Relay Adjust permits adjustment of the pneumatic relay. See page 121.
D Supply Pressure permits calibrating the supply pressure sensor. Normally the sensor is calibrated at the factory and
should not need calibration. See page 122.
D Pressure A permits calibrating the pressure A sensor. Normally the sensor is calibrated at the factory and should not
need calibration. See page 123.
D Pressure B permits calibrating the pressure B sensor. Normally the sensor is calibrated at the factory and should not
need calibration. See page 123.
D PST Calibration permits running a PST calibration. See page 124.
Note
The transducer block mode must be set to manual and the protection set to None before the instrument can be calibrated.
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.
