Chapter 4: Calibration

4.1 Introduction

The ST60 Compass instrument is set up with factory-programmed default
settings, so in order to optimize 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 key presses and the resulting displays. If a parameter is
adjustable, adjustment instructions are given at the appropriate point on the
diagram.

EMC conformance

• Always check the installation before going to sea to make sure that it is not
affected by radio transmissions, engine starting etc.
• In some installations, it may not be possible to prevent the equipment from
being affected by external influences. Although this will not damage the
equipment, it can lead to spurious resetting action, or momentarily may result
in faulty operation.

4.2 User calibration

The User calibration procedures (see the
to carry out:
• Linearization and heading alignment.
• Locked heading display selection.
• Variation setting.
• True/Magnetic display selection.
User Calibration is possible only if it is enabled (default) in Dealer Calibration.
