Chapter 4: Calibration
4.1 Introduction
The ST60 Wind instruments are set up with factory-programmed default settings, 
so in order to optimize the performance of the instruments 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. Adjustment 
instructions are given as applicable.
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:
• Linearize and align the wind transducer.
• Select the required wind speed units
Linearizing and aligning the wind transducer
This procedure ensures that the sensors in the windvane transducer are correctly 
calibrated to record rotation of the windvane, then compensates for any small 
errors which may exist in the alignment of the wind transducer.
To do this:
1. Power-up the ST60 Wind instrument.
2. Slowly turn the vessel through two complete circles. This procedure automat-
ically linearizes the windvane. A successful linearization is indicated by the 
digital display flashing and the buzzer sounding three beeps.
