Data Log
The Chartplotter can be set to log passage data every 30 minutes. Up to 48
log entries are held. When 48 entries have been saved, the first entries
start being overwritten.
If the number of log entries exceeds the table size, use the trackpad
up/down to scroll the list and view further log entries. Each line in the log
shows:
• Time of log entry
• Position at time of log entry
• Course Made Good (CMG) since last log entry
• Distance Made Good (DMG) since last log entry
You can stop the log at any time and you can clear the log from memory.
➤ To use Data Log Mode:
1. Press
DISPLAY repeatedly until the Data Log table is displayed.
2. Press the
START LOG soft key to start logging; the START LOG soft key
changes to
STOP LOG.
At 30 minute intervals, the current time, vessel’s position, distance made
good (DMG) and course made good (CMG) are recorded as shown in
Figure 3-20.
