Chapter 4: Calibration
4.1 Introduction
The ST60+ Speed instrument is set up with factory-programmed default settings,
so in order to optimise the performance of the instrument on board a particular
vessel, the procedures in this Chapter must be carried out immediately after the
completion of installation, and before the equipment is used for navigational
purposes.
Where practicable, the calibration procedures are presented diagrammatically, to
show the sequence of button presses and the resulting displays. Adjustment
instructions are given where applicable.
4.2 User calibration
The User calibration procedures enable you to:
• Set the required units for speed readings.
• Set the required Log units.
• Set the speed resolution.
• Set the speed readings on the instrument to be a true indication of the actual
speed of the vessel.
• Select temperature units.
• Calibrate for correct temperature readings.
• Set timer buzzer on or off.
• Set pop-up pilot display on or off.
To carry out a User calibration:
1. Power up the ST60+ Speed instrument.
2. Hold down the
speed and trip buttons for approximately 2 seconds so that
the User calibration entry screen is displayed.
3. Referring to the
User calibration
diagram, carry out the calibration proce-
dure. Use the
speed button to move from screen to screen and the timer and
reset buttons to set the required values (except Adjust to SOG display).
Set speed units
Select either KTS (knots), MPH (miles per hour) or KMH (kilometers per hour),
as required.
