12.5C50, calibration of wind

12.5.1C50 (RET)

To return to the normal mode, press SET.

12.5.2C51 (PAGE ATO)

This setting allows you to display the Navigate page or not.

PAGE ATO	Page automatically on if Compass transducer or
	GPS is connected
PAGE ON	Page is always on
PAGE OFF	Page is always off

12.5.3C52 (OFF TWA)

Select true (TWA)or the apparent wind angle (AWA) as main- function under WIND. The optional analogue wind instrument will display the same selection. All Multi Control instruments which have the calibration code C63 set to (WIA) will display what is selected in C51.

C51 (OFF) = Apparent wind angle displayed.

C51 (ON) = True wind angle displayed.

12.5.4C53 (Unit m/s)

Unit for wind speed. Metre/second (m/s), knots (KTS) or Beaufort (BF).

12.5.5C54 (1.70 CAL)

Use 1.50 for a single fin transducer (with two propeller blades) Use 1.70 for a twin fin transducer (with three propeller blades)

12.5.6C55 (000° ADJ)

Mast top unit misalignment adjust value or the so called ”A-fault”, makes it possible to choose any horizontal angle.

Example: If the wind angle is +4° when you sail/drive the boat straight into the wind. Set the calibration channel C54 to 356°.

12.5.7C56-C63 Wind calibration values

In channels C55 to C62 you set the calibration values for the mast top unit. Each mast top unit is individually calibrated for best accuracy.

See the separate wind calibration certificate supplied with each mast top unit. Each of the inter-cardinal directions are calibrated:

C55 (000° 000)
C56 (045° 045)
C57 (090° 090)
C58 (135° 135)	Set the calibration values according
