4.2 User calibration
The User calibration procedures enable you to:
• Set the required units for depth readings.
• Set the offset for depth readings, i.e. determine whether depth
readings are from the keel of the vessel or from the water line.
• Lock the shallow alarm.
• Set the required units for speed readings.
• Set the speed resolution.
• Select the log distance units
• Either calibrate the speed reading to Speed Over Ground (SOG) or
manually apply a calibration factor, to obtain correct speed through
the water.
• Select temperature units.
• Calibrate for correct temperature readings.
• Set timer alarm buzzer on or off.
Separate routines are provided for the User calibration of the depth and
speed functions. To carry out either of these routines:
1. Power up the ST60 Tridata instrument.
