Supply Pressure
Note
The pressure sensor is calibrated at the factory and should not require calibration.
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.
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. When supply pressure is at 0 psi, press OK to continue. 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. When supply pressure is at 0 psi, press OK to continue. Once calibration is complete, proceed with
step 2.
2. Adjust the supply pressure regulator to the maximum instrument supply pressure.
3. Enter the new supply pressure (in psi) using the external pressure gauge value. Press OK.
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 Transducer Block mode in Auto for the valve to track input.
6. Calibration is now complete. Press OK.
