20 Pathfinder Smart Heading System - Owner’s Handbook
3 Calibration
3.2 Calibrating with a Pathfinder Plus display
Step 1: Enter Compass Setup mode
1. Press the MENU button.
2. Press the SYSTEM SET UP soft key. You will then see the SYSTEM SET UP
MENU.
3. Select COMPASS SET UP from the menu:
• COMPASS SETUP is not visible when you first access the SYSTEM
SET UP MENU – you will need to scroll down the list
• use the trackpad to move to the bottom item in the box, then
continue moving down the list to select COMPASS SET UP
4. Press the COMPASS SET UP soft key. You will then see the COMPASS
SET UP box.
The COMPASS SET UP box contains four items:
• HEADING = the current heading from the Smart Heading System (if
there is no heading figure displayed, check your compass
connections)
• COG = Course Over Ground heading from GPS (if connected)
• SOG = Speed Over Ground from GPS (if connected)
• CORRECTED DEVIATION = the amount of deviation corrected during
compass linearisation
At this stage, because you have not calibrated the Smart Heading System:
• HEADING and COG will differ
• CORRECTED DEVIATION will show dashes instead of a value
Note: Press ENTER or CLEAR if you need to return to the SYSTEM SETUP
MENU at any time.
