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 cali-
bration 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.
