Chapter 4: Calibration

4.1 Introduction

The ST60+ Tridata 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 as applicable.

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

• 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 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.

2. Hold down the

depth and speed buttons for approximately 2 seconds so

that the User calibration entry screen is displayed.

3. Carry out the User calibration procedures for

Depth

and

Speed
