Log Calibration Method
Set your log to zero and travel a known distance
between two points.
If there is any tidal current,
you should travel the same course in both
directions to find the average distance.
You may calculate a correction factor as follows:
Known distance
correction factor =
distance from log
For example, if you have travelled over a known
distance of 1 mile but your log reading is 0.8,
giving a correction factor of 1.25. Therefore, your
correct boat speed will be the indicated speed
multiplied by 1.25.
Enter the simulation mode by holding the key
at power up, When speed is selected in the
simulator mode the display will indicate a fixed
calibration speed, for example 10.0 knots.
Follow the Secondary Functions chart to reach
Speed Calibration mode.
Use the to set the displayed speed to the
new value. For our example, this new speed
would be 10.0 x 1.25 which is 12.5 knots.
