3-Point Calibration
3-point calibration is designed for tanks that vary in shape from the top
to the bottom. You can begin calibration at any point in the 3-point
process, but we recommend starting calibration with an empty tank.
In a 3-point calibration, you will set three points, one each for empty,
half and full levels.
