For the selected engine, you can enter:
From tank: The fuel tank the engine is connected to.
Flow filter: Most engines do not draw fuel from the tank at a steady rate. To give a stable fuel flow reading, the TRACKER calculates the flow by taking several measurements and averaging them. Use the Flow filter to set the period over which the fuel flow is averaged.
The Flow filter can be set from 0 to 30 seconds. Use the lowest value which gives a stable flow.Usually a value of 5 to 10 seconds will give a satisfactory result for
This setting affects the Fuel flow and Fuel economy reading on the Fuel window but it does not affect the Fuel used reading.
Setup tanks
If the boat has more than one tank, select Tank and select each tank in turn.
For the selected tank, you can enter:
Add fuel, Fill tank, Set remaining:
See section 12-3.
Tank alarm: See section 12-4.
Tank size: The tank capacity. Northstar recommends measuring tank size by draining the fuel tank, filling it to capacity and using the fuel dispenser’s reading. Beware of air pockets, especially in underfloor tanks.
