Chapter 4 - Troubleshooting
Calibrating the ADU Gyros
The SAILOR 700 VSAT ADU’s gyros continuously measure the motion of your vessel
and send this data to the ADU’s motor control circuitry to keep the ADU pointed at
the satellite. At the factory, each ADU gyro is precisely calibrated to work with the
ADU’s circuit board. Therefore, if you ever have a gyro or circuit board replaced,
you will need to recalibrate the gyros for the new part.
Follow the steps below to calibrate the gyros.
1.
Press MENUS until the display shows “DIAGNOSTICS.”
2.
Press ACCEPT to enter the Diagnostics menu.
3.
Press CHANGE until the display shows “CAL GYRO= YES.”
Calibrate the gyros only if directed by Thrane & Thrane Technical Support, and
only while the vessel is stationary. A poor gyro calibration can reduce the
performance of the ADU.
