speed calibration
Speed calibration sets the units of measurement, damping and speed calibration factor
units
Boat speed values can be shown in knots, kph or mph. To change the units, highlight Unit and press
ENTER. Using the UP/DOWN keys, highlight the desired choice and press ENTER to memorise.
damping
Boat speed damping allows you to slow down the response of speed readings in rougher conditions
by adjusting the damping value from 0 to 9. For minimum damping, set the value to 0, for maximum
damping, set the value to 9.
adjustment
Speed adjustment calibration is necessary to compensate for hull shape and paddlewheel location on
your boat. For accurate speed and log readings, it is essential that the paddlewheel is calibrated.
adjustment - auto
This procedure will automatically calibrate the boat speed and log readings ,and is the recommended
method for most boats. This procedure requires the boat to make consecutive runs, under power at a
constant speed, over a known distance.
Select two markers that are easily identifiable on the ground and on a chart, and where the effects of tidal
flow is at a minimum. Measure and record the distance between the markers on the chart.
It is recommended that three runs are carried out, this accounts for tidal efforts, and improves accuracy.
However, a time should selected when the current is at a minimum, i.e. slack water between tides.
1) From the Speed Calibration Menu, highlight Adjustment , choose auto from the drop-down box, and
then press the ENTER key to confirm.
2) If necessary, adjust the Run Length to correspond with your measured distance and then highlight OK,
and press ENTER to accept.
3) The display will now show Run 1 and start will be highlighted. Maintaining the boat at your constant
speed, press ENTER when the boat is in line with the start of your measured distance. The display will
now change to show Run 1 with
end highlighted.
4) When the boat is in line with the second marker of your measured distance, press the ENTER key to
temporarily halt the calibration. Run 2 and
start will now be shown on the screen.
5) Maintaining your constant boat speed, turn the boat through 180 q in preparation for your second run
along the measured distance. When the boat is in line with the second marker, press the ENTER key to
resume the calibration procedure. The display will now show RUN 2 and
end will be highlighted.
6) When the boat is in line with the first marker, press the ENTER key. This will temporarily halt the
calibration procedure.
7) Repeat the procedure detailed above for Run 3 .
8) Upon completion of Run 3, highlight accept all and press ENTER. The system will now automatically
calculate the new boat speed and update the readings accordingly.
