WTP system
7.5
heel_off
is the offset value for the heel sensor. If the heel
angle doesn't read 0 when the boat is sitting upright
in the water, the necessary correction must be
entered here.
Heading_o
is the offset value for the compass. A positive
heading offset will increase the reading of the
compass heading. The best way to calibrate this is
to correct the compass bearing being received so
that it matches known transits on the shore.
forestay
calibration for the forestay load fitting. Wind up the
backstay or runner to a known tension, then enter
this value here.
Settings
The Settings option is specific to the WTP. The boat length, mast height
and variation calibrations are self-explanatory. The leewaycal is a
leeway calibration value—a figure between 3 and 5 should be
appropriate for modern boats. The use_heel gives you the option of
excluding heel sensor data from the calculations, by entering zero
here—if you do not have a heel sensor fitted or it breaks. The two
additional settings to be specified control the automatic switching of
variables on the displays according to your point of sailing: updownang
allows you to specify the true wind angle at which the displays will
switch from upwind to downwind settings; osctime allows you to
change the frequency with which the displays switch between the
selected variables (units here are 1/10
ths
second).
Bounds
The bounds checking function works in exactly the same way as for
h2000 instruments, as described above.
