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.
