1/2 tank, 3/4 tank, and a full tank) will provide a more accurate reading than entering two calibration points (empty tank and a full tank).

Tip: For a quick calibration, start with an empty tank, and enter calibration points as you fill up the tank.

Specify the capacity of your tank. To do so, on your chartplotter or marine instrument, go to the configuration options for NMEA 2000 devices.

Customizing the GFS 10

If using more than one GFS 10 for multiple engines or fuel tanks, on your Garmin chartplotter or marine instrument, go to the configuration options for NMEA 2000 devices to select the engine and tank associated with each GFS 10.

If the fuel-flow information received from the GFS 10 appears inaccurate, you can optionally calibrate the fuel-flow sensor from the configuration options for NMEA 2000 devices on your Garmin chartplotter or marine instrument. You can manually enter a positive or negative adjustment, if needed.
