1.8 How to Set the Ship’s Heading
The current indicator has a NAV mode which measures tides in deep waters where
ground tracking is not available. To achieve reliable measurements, however, you
must feed accurate heading (gyro) data and ship’s position (or speed and course) data
to the current indicator.
1. Confirm that the gyro has settled and all necessary compensations (latitude com-
pensation, weather compensation, etc.) have been made correctly.
2. Adjust the AD Converter to show the same reading shown on the master gyro-
compass. Do not make the adjustment while the ship is turning.
If the gyro reading is accurate, the current indicator will provide accurate tide informa-
tion. If gyro data is wrong, the following symptoms will appear.
• The drift angle in the ground tracking mode is not the same as that in the nav mode
or is shown in the direction reverse of the actual direction.
Drift angle in ground tracking mode: Difference between ground speed and course
and gyro heading.
Drift angle in nav mode: Difference between nav course and gyro heading.
• Tide speed and direction in the ground mode is not the same as that in the nav
mode. And the tide correlation (relative angle, size) between layers is different.
If you encounter such symptoms calibrate the current indicator as shown in the instal-
lation manual.
