Log calibration

The ST30 Speed should not be used for navigational purposes until the

transducer paddlewheel has been calibrated to suit the characteristics of

the vessel.

This is a simple operation and is carried out as follows:

1. Choose two charted points that are approximately 1nm apart.

Approximately 1Nm

Point 1 Point 2

D699

2. Choosing a time when the tidal flow is at a minimum, go from point 1

to point 2 and record the ST30 Speed trip distance.

3. Go from point 2 to point 1 and record the trip distance.

4. Add the two distances together and divide by two to obtain an

average distance.
