Configuring the Sensitive elements
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 packaging, 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.
The parameters are loaded into the Control unit from the Extension menu
as described below:
