3.2.4 Log AUTO CAL Facility
This facility enables the user to calibrate the yacht's log accurately
and simply as all calculations are performed internally by the Main
Processor. Referring to the Fig 3.1, A and B are the two markers
for each run and X is the actual distance for each run as
ascertained from the chart.
Fig 3.1 - Log Calibration Runs
The user is required to enter the distance X in nautical miles (CAL
DIST) and then, as the yacht passes marks A and B on each run,
to instruct the system to start (STRT RUN) and stop (STOP RUN)
and finally to end calibration (END CAL) after the last required run
is complete.
Note
The calibration process can be cancelled at any time during the
operation by pressing the Page Key if the operator is not satisfied
with the calibration runs underway, e.g., hampered by another
vessel or wash, etc.
