Supply Pressure Sensor Calibration - Fisher FIELDVUE DVC6200 Instruction Manual

1. Adjust the supply pressure regulator to the
maximum instrument supply pressure. Press OK.
2. The instrument reduces the output pressure to 0.
The following message appears.
Use the Increase and
Decrease selections
until the displayed
pressure matches the
output x pressure.
Press OK when you have read the message.
3. The value of the output pressure appears on the
display. Press OK to display the adjustment menu.
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.
If the displayed value does not match the output
pressure, press OK, then repeat this step (step 4) to
further adjust the displayed value. When the displayed
value matches the output pressure, select Done and
go to step 5.
5. The instrument sets the output pressure to full
supply. The following message appears.
Use the Increase and
Decrease selections
until the displayed
pressure matches the
output x pressure.
Press OK when you have read the message.
6. The value of the output pressure appears on the
display. Press OK to display the adjustment menu.
7. From the adjustment menu, select the direction and
size of adjustment to the displayed value. If the
displayed value does not match the output pressure,
press OK, then repeat this step (step 7) to further
adjust the displayed value. When the displayed value
matches the output pressure, select Done and go to
step 8.
8. Place the instrument In Service and verify that the
displayed pressure matches the measured output
pressure.

Supply Pressure Sensor
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,
Press Sensors (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.
