EP-15 Fluid Level Calibration
The default calibration for the EP-15 Fluid Level is just as accurate as
standard fluid level gauges. If, however, the tank has an irregular
shape or greater accuracy is needed, calibration is recommended. There
are three calibration options: 2-Point, 3-Point and 5-Point.
2-Point Calibration
A 2-point calibration is best suited for rectangular or square-shaped
tanks, where the capacity of the top half of the tank matches the capac-
ity in the lower half of the tank. In a two-point calibration, you will set
two points, one each for empty and full levels.
You can begin calibration at either of the two points, but we recom-
mend starting with an empty tank. You will fill the tank to complete
calibration.
