Track Setup - Navman Tracker 5430 Installation And Operation Manual

Fuel Cal
Without calibration the error in fuel
measurements can be up to ± 10%. Calibration
can reduce the error substantially. For twin
engine installations calibration of each
transducer is required.
Calibrating the fuel transducer requires accurate
measurement of the fuel used. This is easiest with
a small portable tank. It should be noted that due
to air pockets, it is very difficult to fill underfloor
tanks to the same level twice. At least 15 litres (4
US gallons) should be used to ensure an accurate
calibration. (The more fuel used, the more
accurate the calibration will be.) Each transducer
in a twin engine installation must be calibrated
separately. This may be done at the same time
with two portable tanks, or at different times
using one tank at a time.
The procedure is:
1 Select Clear Used to set Used to zero.
2 Connect the measurement tank(s) to the
engine(s) via the fuel transducer(s).
3 Run the engine(s) at normal cruising speed
until at least 15 litres (4 US gallons) is indicated
(30 litres [8 US gallons] for twin engines).

13-5 Track setup

Tracking records and displays the boat's course
on the chart (see section 3-5).
Record
Off: The TRACKER stops recording a track.
1 to 5 (select a track number): The TRACKER
starts recording the boat's course into the
selected track.
Display
Off: No track is shown on the chart.
1 to 5 (select a track number): The selected
track is shown on the chart.
Plotting Interval
The options are Distance or Time.
Distance
Select the distance plotting interval: 0.01, 0.05,
0.1, 0.5, 1.0, 2.0, 5.0 or 10.0 distance units.

4 Check the actual amount of fuel used per
engine. The easiest way to do this is to refill
the tank(s) to the original level(s) and record
the value(s) shown on the fuel dispenser.
5 Select Fuel Cal. The amount of fuel that the
TRACKER has measured is displayed. Change
the number to the actual fuel amount used.
(Repeat for the other engine in a twin engine
installation).
Flow Filter
Normally engines do not draw fuel from the tank
at a steady rate. To give a stable fuel flow reading,
the TRACKER calculates the flow values by taking
several measurements and averaging them. The
flow filter sets the period over which the fuel
flow is averaged, and can be set from 1 to 180
seconds or Off.
Set the flow filter to the lowest value which give
a stable flow. Usually a value of 10 to 15 seconds
will give a satisfactory result for carburettor
engines. Fuel injected engines may require a
larger value.
This setting affects the Flow rate and Economy
displays. It does not affect the fuel used
measurement.
Time
Select the time plotting interval: 1, 5, 10 or 30
seconds or 1 minute.
Memory used
The percentage of memory used in the track
being recorded.
Tip: Use the user card display to check the
number of points recorded in each track (see
section 11).
Send track
Sends track data on the serial port.
Delete track
1 Select the track number to delete (1 to 5).
2 Select Yes to confirm.
The data in the selected track is deleted.
