4. IMPORTANT NOTICE ON TIDE MEASUREMENTS In the nav aided mode tide accuracy depends heavily on gyro accuracy SETTING SHIP S HEADING The 80 has the nav aided mode to measure absolute tides even in deep waters where ground tracking is unattainable To achieve reliable measurements however you must supply accurate heading gyro information and ship s position or speed course data to the 80 If you are going to use the nav aided mode set the reading of the AD converter gyro interface exactly with that of the master gyrocompass Procedure 1 Confirm that the gyrocompass has settled and all the necessary compensations latitude compensation weather compensation etc are made correctly 2 Operate the AD converter to obtain the same reading as you read on the master gyrocompass Do not make adjustment while the ship is turning Master Gyrocompass 2 o Gyro Interface Figure 9 If the gyro reading is accurate the 80 should provide accurate tide information If the gyro data contains some error however you may see the following symptoms e Set drift information on the nav aided mode differs from that on the ground tracking mode e Tide tide differential information on the nav aided mode differs from that on the ground tracking mode NAV Mode GT Mode NAV Mode Figure 10 10 The 1 80 mainly consi
