h2000 calibration is an ongoing process and is something
you must be aware of each time you go sailing. This is
particularly relevant of the true wind calibration, where
constant refining will pay huge dividends in accuracy. To
this end the process has been simplified as far as possible,
so that all you require for accurate instrument data is some
background knowledge together with a few simple
techniques. Refer to Chapter 3 - Calibration.
1.6 DAMPING
Another important facility that you need to be constantly
aware of is the damping available on certain functions. This
allows you to filter signal noise on the function when in
unstable or rough conditions. The damping works by
applying a filter over a time period; the more you increase
this time period, the smoother the data readings will be, but
the longer it will take to see the effect of any change.
Similarly the lower the time period the greater the jumps
you will see in the numbers, but the response to any change
will be faster.
Dynamic Damping adjusts your system to deliver the most
accurate and real-time information, i.e. when on a beat, it is
essential that the wind angle information is accurate but
steady with most ‘noise filtered out, however, when tacking,
data needs to be more real-time. With Dynamic Damping,
the damping value applied will reduce to almost zero during
conditions when the data is changing rapidly.
The Damping value is set (in seconds) to a steady state
value, the Dynamic Damping is set to a value between 0
(off) and 10 (maximum), the higher the value, the more
sensitive the function is to rates of change, and the faster the
damping value is lowered. This allows the effects of the
change to be more readily seen on the instruments. As the
rate of change of the function reduces, so the damping value
is allowed to rise to the preset Damping Value to ensure
signal noise is filtered out of the data.
