Flow filter:
Most engines do not draw fuel from
the tank at a steady rate. To give a stable fuel
flow reading, the 5507/5607 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 two-stroke carburettor
engines. Fuel injected or four-stroke engines may
require a larger value.
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 10-3.
Tank alarm:

Tank size:
The tank capacity. NAVMAN
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.
Diesel sensors
If the boat has more than one diesel engine and
has NAVMAN diesel sensors, set up the diesel
