3.5.2 “Measured Mile”
This procedure automatically calibrates the speed sensor by
measuring the average time to cover a known distance and
comparing this with the time it should have taken to cover this
distance at the measured boat speed (Fig 3.9) -
From this the error is automatically calculated and used to
adjust the speed sensor data.
Select the “LEG1” option in the speed cal menu. Do not press
at this point.
The display will show “---” and “LEG1” (Fig 3.10) -

NOTE The measured distance used in the calibration procedure will
depend on the units selected (see Section 3.1) -
- If distance units are Nm, then measured distance is 1Nm.
- If distance units are Km, then measured distance is 1Km.
