Averages
An=seconds
or An=-secondsThis function allows you to change the damping constant the system uses on many of the displays. The damping only affects the displays, and not the calculations. The argument <seconds> is the number of seconds it takes for the display <var> to go from an old value, 64% of the way to a new value. For example, if you set the boatspeed average to 10 seconds, and suddenly start traveling at 10 knots from rest, the boatspeed indicator would take 10 seconds to go from 0.00 knots to 6.40 knots. The table below gives the variables associated with each value of <var>, and the associated default value of <seconds>; the values the system uses unless you change them. Once you change a value, it will remain changed as long as the battery backup keeps the variable memory alive. For example, to change Boatspeed averaging to 6 seconds, send "A0=6".
On T1 systems, all averages are enumerated on the Status1 output.
On the T1, A<n>=0 sets averaging to none. Sending A<n>=-<seconds> (negative) switches the averaging function to butterworth filter with 3db point at <seconds>. Butterworth filters have a faster rolloff than conventional averaging (i.e. you get faster response and less delay, but there may be overshoot).
On the 001, the value of A can not be less than 1, and is an integer (i.e. A1=1.5 is A1=1).
