Calibration of EP Devices

Calibrating Fluid level is an important step to ensuring the status of
your tank is correctly transmitted over the NMEA 2000 bus.
For example: if you have an odd-shaped tank, like one that is wider at
the top than at the bottom, the float inside the tank will tell you there
is a half tank of gas when it reaches the midpoint of the tank,
regardless of the tank's actual capacity below the midpoint. That could
cause you to run out of gas more quickly than expected. Whether the
tank is configured for Fuel, Fresh Water, Waste Water, Black Water or
Oil, calibrating the Fluid Level protects you from unpleasant surprises.
