5.2.4.6 CAT6 Ethernet Cable
The CAT6 Ethernet cable (pn 28899) is a 61 cm (2 ft), unshielded CAT6
network cable with RJ45 connectors. It is typically used to connect the HUB-
CPI to the CPI port on a datalogger such as the CR6.

6. Specifications
The CSAT3B measures wind speed and the speed of sound along the three
non-orthogonal sonic axes. The wind speeds are then transformed into the
orthogonal wind components u
x
, u
y
, and u
z
, and are referenced to the
anemometer head. The reported ultrasonic air temperature (T
s
) is the average
between the temperatures computed for the three non-orthogonal sonic axes.
The vector component of the wind that is normal to each sonic axis (such as a
crosswind) leads to a measurement error that is corrected online by the
