speed calibration
Speed calibration sets the units of measurement, damping and speed calibration factor

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.

s ,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
g
round 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.

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

along the measured distance. When the boat is in line with the second marker, press the

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.
