Output Pressure Sensor
To calibrate the output pressure sensor, connect an external reference gauge to the output being calibrated. The
gauge should be capable of measuring maximum instrument supply pressure. Depending upon the sensor you wish to
calibrate, select either Output A Sensor or Output B Sensor. Follow the prompts on the Field Communicator display to
calibrate the instrument's output pressure sensor.
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. Follow the prompts on
the Field Communicator display to calibrate the instrument's supply pressure sensor.
