5-Point Calibration 
5-point calibration is best suited tanks that vary greatly in shape from 
top to bottom. You can begin calibration at any point in the 5-point 
calibration process. We recommend starting calibration with an empty 
tank. In a five-point calibration you will set five points: Empty Level, 1 
Qtr Level, Half Level, 3 Qtr Level and Full Level.  
In a 5-point calibration, you will have four calibration points left after 
calibrating your tank's Empty Level. To figure out how much fuel you 
should add for the remaining steps of the calibration process, divide the 
total capacity of you tank by four. So, if you have a 40-gallon tank, each 
quarter tank will equate to 10 gallons.
