The Electronic pressure calibration points (ua1l, ua1h, ua2l and ua2h)
are used to calibrate the pressure transducer in the dispenser’s utility manifold.
ua1l is the lower pressure calibration point and ua1h is the upper pressure
calibration point. The current calibrated pressure is displayed in the unit price window
ua2l and ua2H are relate to the second pressure transducer.
See pressure calibration procedure for details on how to calibrate the pressure
transducer.
Note changing these values while not calibrating the pressure transducers will cause the
pressure readings to be incorrect
