Configuring the gyro system
Each Sensitive element is tuned to its Master compass before it
is shipped from the factory. This tuning is reflected in a set of
parameters specific for this gyro compass. These parameters are
included in the sensitive element’s package, and they have to be
entered into the Control unit as part of the gyro compass’
installation procedure.
Parameters used for time settings should also be entered. These
parameters are essential when monitoring the occurrence of
alarms.
