DVC6000f Series
Calibration
When a DVC6000f Series 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 instrument. For remote-mounted
digital valve controllers, the Type DVC6005f base unit
ships separately from the control valve and does not
include tubing, fittings or wiring.
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, (either auto or
manual) then calibrate travel by selecting Auto Tvl
Calib or Manual Tvl Calib. For more detailed
calibration information, refer to the following calibration
procedures, available from the Calibrate menu:
D Auto Travel Calibrate—This procedure
automatically calibrates the travel. The calibration
6
procedure uses the valve and actuator stops as the
0% and 100% calibration points.
D Manual Travel Calibrate—This calibration
procedure allows you to manually determine the 0%
and 100% calibration points on the valve.
D Relay Adjustment—This procedure permits
adjustment of the pneumatic relay when switching
from single-acting to double-acting or back.
D Travel Sensor Adjust—This procedure permits
calibrating the travel sensor. Normally the travel
sensor is calibrated at the factory. Calibrating the
travel sensor should only be necessary if the travel
sensor is replaced.
D Supply Pressure Sensor Calibrate—This
procedure permits calibrating the supply pressure
sensor. Normally this sensor is calibrated at the
factory and should not need calibration.
D Output A Sensor Cal—This procedure permits
calibrating the Output A Sensor. Normally this sensor
is calibrated at the factory, and should not need
calibration.
D Output B Sensor Cal—This procedure permits
calibrating the Output B sensor. Normally this sensor
is calibrated at the factory, and should not need
calibration.

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 may
move. To avoid personal injury and
property damage caused by the
release of pressure or process fluid,
provide some temporary means of
control for the process.
Travel Calibration
There are two procedures available for calibrating
travel:
D Auto Travel Calibration
D Manual Travel Calibration
