Calibration
September 2013 5-7
Supply Pressure Sensor Calibration
Note
Supply Pressure Sensor Calibration is
not available for instrument level HC.
To calibrate the supply pressure sensor, connect an
external reference gauge to the output side of the
supply regulator. The gauge should be capable of
measuring maximum instrument supply pressure.
From the Calibrate menu, select Sensor Calibration,
Pressure Sensors, and Supply Sensor. Follow the
prompts on the Field Communicator display to
calibrate the instrument’s supply pressure sensor.
1. Select a) Zero Only, or b) Zero and Span (gauge
required).
a. If Zero Only calibration is selected, adjust the
supply pressure regulator to remove supply
pressure from the instrument. Press OK. Once
calibration is complete, go to step 5.
b. If Zero and Span calibration is selected, adjust
the supply pressure regulator to remove supply
pressure from the instrument. Press OK. Adjust the
supply regulator to the maximum instrument supply
pressure. Press OK. Proceed with step 2.
2. The following message appears:
Use the Increase and
Decrease selections until
the displayed pressure
matches the instrument
supply pressure.
Press OK when you have read this message.
3. The value of the pressure appears on the display.
4. From the adjustment menu, select the direction and
size of adjustment to the displayed value. Selecting
large, medium, and small adjustments causes
changes of approximately 3.0 psi/0.207 bar/20.7 kPa,
0.30 psi/0.0207 bar/2.07 kPa, and 0.03 psi/0.00207
bar/0.207 kPa, respectively. Adjust the displayed value
until it matches the supply pressure, select Done and
go to step 5.

5. Place the instrument In Service and verify that the
displayed pressure matches the measured supply
pressure.
Travel Sensor (1-3-2-2)
The travel sensor is normally adjusted at the factory
and should not require adjustment. However, if the
travel sensor has been replaced, adjust the travel
sensor by performing the appropriate procedure. See
the Maintenance section for travel sensor replacement
procedures.

WARNING
Failure to remove air pressure may
cause personal injury or property
damage from bursting parts.
1. Remove supply air and remove the instrument from
the actuator.
2. As shown in figure 5-2, align the feedback arm (key
79) with the housing by inserting the alignment pin
(key 46) through the hole marked “A” on the feedback
arm. Fully engage the alignment pin into the tapped
hole in the housing.
