Waves and wind cause the boat speed to fluctuate
slightly. To give a stable reading, the NS3100
Multi calculates the boat speed and trim speed by
measuring the speed several times and averaging
the measurements. The speed damping value ranges
from 1 to 5:
A lower value averages readings over a shorter
period of time. This gives the most accurate speed
but has the most fluctuations.
A higher value averages readings over a longer
period of time. This gives the most stable speed
but will ignore some true speed changes.
Set the speed damping to the lowest value which
gives a stable speed reading. Values of 1, 2, 3, 4
and 5 average readings over a time period of 6,
12, 18, 24 and 30 seconds respectively. To get the
most accurate, stable trim speeds, you may need to
increase the damping. To set speed damping:
This sets how speeds are displayed. It has two
settings:
0.0 Displays speeds as 0.0 to 19.9, 20 up.
0.00 Displays speeds as 0.00 to 19.99, 20.0 to
29.9, 30 up.
