Horizontal wind speed
Shows the wind speed in the U / V Plane
. See Fig 2.
Vertical wind speed
Shows the magnitude of wind speed in the W axis
. See Fig 2.
Units
The Units identifier shows the units in which the wind speeds are measured.
Units
Identifier

F
Speed of Sound (SOS)

Output rate
(
not displayed)
The WindMaster delivers wind information at rates from 1 (default setting) to 32 outputs / second.
[The sample rate (20 or 32 Hz) is chosen automatically to be an appropriate multiple of the output rate.]
Data can be instantaneous or averaged (see section 10).
NOTE use at least 38400 baud if high output rates 20/32Hz are used with all parameter outputs on.
