Selecting the Differential Pressure tab shows this dialog:
Connect the valve to a fluid source to calibrate its differential pressures, the difference between measurements at sensor A and B, at each flow setting. As each range is reached its Set button becomes active. Set the calibration value for each pressure value and press Save to Hardware to upload the values to the valve. Press Save to File to create an archive for use if the electronics are replaced. Load the file's values by pressing Load from File. Query the current calibration settings from the hardware by pressing the Load from Hardware button.
