Rudder Calibration (DOCK SIDE/RUDD CAL)
WARNING
This procedure moves the helm, and should only be used when the
vessel is at the dockside. For sterndrive systems, the engines must
be running before you start the procedure.
The Dockside Rudder Calibration function is available when the
ST7000 Plus is used with either an ST4000 Plus or ST5000 Plus
autopilot. It performs an automatic calibration of the rudder range, for
systems with a rudder reference unit. If a rudder reference unit is not
installed, the function determines the helm drive speed.
The auto dockside procedure is not available if the ST7000 Plus is used
with a Type 100/300 Course Computer. If you try to use this function
with a Course Computer, the display shows AUTO N/A.
If you start the procedure by mistake, press any key to cancel it.
BAR OFF: The bar graph is not displayed.
BAR RUDD: This shows the rudder position, and is the default
setting. Note that a rudder reference transducer is required for
accurate rudder position information.
