Chapter 4: Calibration
4.1 Introduction
The procedures in this Chapter must be carried out before the
equipment is used operationally, to optimise the performance of the
instrument with the vessel.
Calibration information is presented in flow chart form. The flow charts
show the various calibration screens and key presses necessary to carry
out calibration. All key presses are momentary unless otherwise stated.
EMC conformance
• Always check the installation before going to sea to make sure that it
is not affected by radio transmissions, engine starting etc.
4.2 User calibration
User calibration enables you to:
• Set the wind angle and speed response values. Use higher response
values for rapid updates in reasonable weather conditions (for
example, when you are trying to maintain a locked course). Use
lower response values in squally conditions to damp out unstable
readings.
• Set the required wind speed units, either
KTS
(knots) or
M/S
(metres
per second).
• Linearise and align the wind transducer.
Power up the instrument then follow the procedure in the User
calibration flow diagram.
