ONNECTION
Connect the outputs according to one of the two schemes below, depending on the output
type, current (standard) or voltage (on request), available in the instrument.
OUT 1 and
OUT 2 are associated to wind speed and direction respectively. In order to change the type of
speed and direction measurements associated to the outputs (e.g., to associate to the outputs
the U-V Cartesian components), see chapter 6
.
