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 calibra-
tion at either of the two points, but we recommend starting with an 
empty tank. You will fill the tank to complete calibration.
