Wind Offset
Note ! This offset only applies if you have a wind transducer directly
connected to SimNet (IS12TW) or a wind transducer that outputs
data on NMEA2000 format.
The Wind Offset feature allows you to correct for a fixed wind
angle offset. Steer the boat directly into the wind with a damping
of 15s. Keep the bow at a steady heading for 15-20 sec. and read
the wind angle. If necessary press the
PORT 10 or STBD 10
buttons to input an off set that makes the display read Wind
000°.
The Offset value can be either
positive or negative.
Wind damping
Damping of the apparent wind angle
is made by the Advanced Wind Filter
(AWF) in the Autopilot Computer.
The inputs to the AWF are heading,
boat speed, apparent wind angle and
wind speed. Verify that these inputs
are available in User Setup/Source
Select (page 27).
The boat speed input to the AWF is Speed Over Ground (SOG)
or speed through water. If none of these are available, the AWF
will use a boat speed that is 1.5 times the Transition Speed set in
the Installation/Seatrial menu.
Range : 1 – 100 seconds
Default : 15 seconds
Use the PORT 10 or
STBD 10 button to adjust
Recommended setting for power boats: 1-5 seconds.
Depth Offset
Note ! This adjustment only applies to “smart” depth transducers that
outputs depth on NMEA2000 format. NMEA0183 sentence
‘DPT’ contains offset and the depth reading is from the surface.
