Garmin GFL 10 - Manual (Page 5)

GFL 10 Installation and Configuration Instructions 
Configuring the NMEA 2000 Tank Capacity
You can indicate the capacity of the fluid tank that the GFL 10 adapter is associated with.
1. From the NMEA 2000 Devices list, select the GFL 10 device.
2. Select an option:
For most Garmin chartplotters, select Review > N2K Tank Capacity .
For other Garmin marine devices, select Config > N2K Tank Capacity .
3. Select the tank capacity.
4. Select
Done .
Calibrating the Fluid Level
To use the GFL 10 adapter, you must calibrate the fluid level of the tank that the adapter is
associated with, using a minimum of two calibration points. The greater the number of fluid
calibration points, the greater the accuracy of the reading on the fluid-level gauge.
1. Turn the boat ignition key to the On position (not Start).
2. From the NMEA 2000 Devices list, select the GFL 10 device.
3. Select an option:
For most Garmin chartplotters, select Review > Level Calibration > Add Calibration
Point .
For other Garmin marine devices, select Config > Level Calibration > Add Calibration
Point .
4. Select the percentage of fluid currently in the tank, based on the total tank capacity.
5. Select
Done .
6. Change the level of the fluid in the tank.
7. Select
Add Calibration Point .
8. Select the percentage of fluid currently in the tank, based on the total tank capacity.
9. Select
Done .
10. Repeat steps 6 through 9 to add additional, optional fluid-level calibration points.
Troubleshooting the Tank Number
If multiple GFL 10 adapters are assigned to the same NMEA 2000 fluid type, each adapter is
assigned a unique tank number automatically. If the “Invalid NMEA 2000 tank configuration”
error message appears, you must assign a unique tank number to each adapter.
For example, if two adapters are assigned the NMEA 2000 fluid type value of Live Well and the
error message appears, you must assign each adapter a unique tank number.
1. From the NMEA 2000 Devices list, select the GFL 10 device.
2. Select an option:
For most Garmin chartplotters, select Review > Tank Number .
For other Garmin marine devices, select Config > Tank Number .
3. Select a tank number.
4. Select
OK .
