112 ST6001+ Autopilot Control Unit - Owner’s HandbookGlossaryTerm Meaning° DegreesA AmpAST(Advanced SteeringTechnology)AST (Advanced Steering Technology) is Raymarine’s unique advancedsteering algorithm. It uses inputs from a wide variety of sensors to tune theautopilot’s operation to provide superior control of the boat in any condition.AutoLearn Self-learning calibration feature available on Type 150G and 400G autopilotsystems.AutoTrim The AutoTrim setting determines the rate at which the autopilot applies‘standing helm’ to correct for trim changes caused by varying wind loads onthe sails or superstructure.AWG American Wire GaugeCE Marked on Raymarine products that comply with defined EuropeanCommunity standardscounter rudder Counter rudder is the amount of rudder the autopilot applies to try to preventthe boat from yawing off course. Higher counter rudder settings result inmore rudder being applied.CR pump Constant Running hydraulic pumpDC Direct currentEMC(ElectromagneticCompatibility)When powered up, all electrical equipment produces electromagnetic fields.These can cause adjacent pieces of electrical equipment to interact with oneanother, and this can degrade their performance. By following the EMCguidelines in this handbook, you can minimize these effects by ensuringoptimum Electromagnetic Compatibility (EMC) between equipment.Fluxgate Standard Raymarine compass supplied with course computer core packft Foot (1 ft = 305 mm)GPS Global Positioning SystemGyroPlus Raymarine’s GyroPlus yaw sensor that measures the boat’s rate of turn.
