9.1.9Unit for Air Pressure, C18 (Unit hPA)

Future function. Unit for air pressure. Hecto Pascal (hPa) or Inch

HG (INH).

9.1.10 Unit for Wind Speed, C19 (Unit m/s)

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

Note, this is a local setting and has to be done on both Sea Data and the Wind instrument

9.1.11 Adjustment of Wind Angle, C20 (000° ADJ)

Mast top unit misalignment adjust value or the so called ”A-fault”, makes it possible to choose any horizontal mounting angle. Example 1: If the wind angle is +4° (from Starboard) when you sail/drive the boat straight into the wind. Set the calibration channel C54 to 356°.

Example 2: If the wind angle is -4° (from port) when you sail/drive the boat straight into the wind. Set the calibration channel C54 to 004°.

9.1.12 Damping of Wind Readings, C21 (SEA LOW)

Damping of wind information. Controls the response time of wind changes. To change damping, press SET. To select damping level, press PLUS and select from: LOW) 1 sec, (MED) 5 sec and (MAX) 22 sec. To store the selected value, press SET.

Factory value is (LOW), for use in calm sea. But if the sea is rough, you may want to ”stabilise” the readout on the display, then select MID or (MAX). Damping is set separately for each instrument.
