To set the desired upper reference point do the following:
1. Adjust the Reference Gauge Height to the distance from the tank
bottom to the desired Upper Reference Point.
2. Add the distance between the Upper Reference Point and the
Transmitter Reference Point to the Calibration Offset value that is
stored in the transmitter database.
