Chapter 4: Rudder Angle Instrument
4.1 Getting started
The ST290 Rudder Angle Indicator Instrument provides a real-time
indication of rudder position as determined by the associated Rudder
Reference Transducer.
Figure 4-1: Rudder Angle instrument
Displayed information
The rudder position is indicated by a pointer. The instrument scale range
gives an expanded indication from -40
°to +40°about zero.
4.2 Normal use
As the ST290 Rudder Angle Indicator operates in real time, very little
operator action is necessary during normal use except to observe the
instrument as required to ascertain the rudder angle.
Note:If rudder angle information is not available on the SeaTalk bus, the
analogue pointer oscillates ±10° about the top of the dial.
The /DISP button is used to set the backlighting. The SET, < and >
buttons are not used.
