Select PSI for US units, or Bar for metric units.

This will calibrate the PD sensor. While the controller sensor ports are disconnected from the
hydraulic tubing, select the Calibration = Yes. The calibration occurs very quickly, and the
sensor ports on the controller should be reconnected after passing through this program step.
This will conclude the programming of the controller, and it is ready to use. If you want to revisit

for at least 3 seconds.
