Speedometer - CORRECT CRAFT Ski Nautique Owner's Manual

The speedometer gauge utilizes a LCD display to provide information to the
operator and three push button switches to select the display mode. This
microprocessor-based gauge communicates with the speed transducer
assembly over a serial communication link. The speedometer receives input
via the speed transducer assembly from the two pitot tube pressure sources and
displays the highest of the two sources as the current speed.
The tachometer gauge also utilizes a LCD display and push button switch
arrangement to communicate with the operator. The engine speed input to the
gauge comes directly from the engine ignition system.
The speed transducer assembly connects the two pitot tubes via flexible tubing
and to the speedometer gauge via a four conductor cable. The transducer
converts the pressure at the pitot tubes into digital information that is sent to
the gauge for processing.
Speedometer Operation
The speedometer operates in one of three "modes". These are "Normal
mode", "Competition mode", and "Calibration mode". The operator switches
between modes using the control buttons.
The speedometer powers on in "Normal mode" with the analog speed display,
the digital speed display, and the pitot symbol active. The text line contains
"NAUTIQUES" and the expanded speed display is blank. The analog and
digital speed displays will indicate current speed and the pitot symbol will
indicate which pitot tube is being used. Pressing the mode button once will
cause the gauge to enter "Competition mode". The analog speed display, the
digital speed display, and the pitot symbol will be active as in the "Normal
mode". The text line will display the current speed deviation settings on the
far ends. The minus deviation setting will be displayed on the left side and the
