wind calibration
Wind calibration sets the wind speed measurement units, damping, and masthead unit offset. The
masthead unit offset can be adjusted while observing the live apparent wind angle on the same page
(Refer to the flow chart detailed on Page 20).
wind speed - units
Wind speed values can be shown in knots, kph, mph or m/s. To change the wind speed units,
highlight
Wind speed
from the
Calibration Menu
and press
ENTER
. Next, highlight
Unit
, press
ENTER
and select th e desired choice from the drop- down menu. Press th e
ENTER
key again to
memorise the setting.
wind speed damping
Wind speed damping allows you to slow down the response of wind speed-readings in gusty
conditions by adjusting th e damping value from 0 to 9. For minimum damping, set the value to 0.
Increase the damping value if the readings are too unstable in rough weath er.
wind angle - calibration
Accurate wind angle readings require the masthead unit to be installed facing forward and as close
to the centre line of the boat as possible. However, this is not always possible, so the h1000 allows a
masthead unit sensor offset to be applied. This offset applies an electronic correction so that wind
angle readings are then shown correctly on the display.
MHU offset
is calculated by the following procedure:
1.
Sail close-hauled on a Port Tack and note the set of all sails. When conditi ons are steady, note
the apparent win d angle. For example, Port 35
°
.
2.
Tack the boat until close-hauled on a Starboard Tack, ensure the sails are set as for the Port
Tack. When conditions are steady, note the apparent wind angle. For example, Starboard 25
°
.
3. To
calculate
the
MHU Offset
subtract the Starboard value from the Port value, then divide by
two. For example, Port 35
°
- Starboard 25
°
= 10 / 2 = 5.
If the value is positive the offset is to Port, if the value is negative it is to Starboard.
To enter the masthead unit offset, highlight
Wind angle
from the
Wind Calibration Menu
and press
ENTER
to select. Highlight
MHU offset
and press ENTER.
If the value calculated is positive, the wind sensor is misaligned to Port. To correct this, the value
must be offset clockwise (starboard) by the value calculated. Use the
UP/DOWN
keys and the
ENTER
key to alter the value.
If the value is negative, the wind sensor is misaligned to Starboard. To correct this, the readings must
be offset anti-clockwise (Port) by th e calculated value. Use the
UP/DOWN
keys and the
ENTER
key to
alter the value.
wind angle - damping
Wind angle damping allows you to slow down the response of wind angle readings in gusty conditions
by adjusting the damping value from 0 to 9. For minimum damping, set the value to 0. Increase the
damping value if the readings are too unstable in rough weather.
