Raymarine i60 wind, Installation And Operation Instructions Manual

7.1 User calibration
The i60 CH instrument display is a repeater display
and as such does not require calibration, the steps
below apply to the calibration of the i60 Wind
instrument only.
User calibration options include:
• Wind angle offset — Assigns an offset to the wind
angle readings.
• Units for Wind speed readings — Assigns the unit
of measure used for wind speed related readings
Automatic Linearization
The wind transducer can linearize itself automatically
under certain conditions.
For Automatic Linearization to be performed
CAL
must be flashing on the digital display. CAL is
displayed for approximately 30 seconds after power
on under the following conditions:
• At first power on, after installation
• At power on, after a factory reset.
To perform the automatic linearization the vessel will
need to be underway, with sufficient space to turn in
large circles unhindered. The wind speed must be
sufficient to hold the vane to wind whilst the vessel is
turning. The vessel must be turned slowly through at
least 2 complete circles.

digital display flashing and a buzzer sounding three
