Parameter
& Data Type
Enter
DataType A code to select the data storage format.
Constant Alpha Code Data Format
IEEE4 IEEE 4 byte floating point
FP2 Campbell Scientific 2 byte floating point
DisableVar
Constant,
Variable, or
Expression
A non-zero value will disable intermediate processing. Normally 0 is entered so all inputs
are processed. For example, when the disable variable is ≠0 the current input is not
included in the total. The total that is eventually stored is the total of the inputs that
occurred while the disable variable was 0.
Value Result
0 Process current input
≠ 0 Do not process current input
WindVector (Repetitions, Speed/East, Direction/North, DataType,
DisableVar, Subinterval, SensorType, OutputOpt)
WindVector processes wind speed and direction from either polar (wind speed
and direction) or orthogonal (fixed East and North propellers) sensors. It uses
the raw data to generate the mean wind speed, the mean wind vector
magnitude, and the mean wind vector direction over an output interval. Two
different calculations of wind vector direction (and standard deviation of wind
vector direction) are available, one of which is weighted for wind speed.
Parameter
& Data Type
Enter
Repetitions
Constant
The number of wind sets (speed/direction or East/North) to calculate results for.
Speed/East
Dir/North
Variables or
Arrays
The source variables for wind speed and direction or, in the case of orthogonal
sensors, East and North wind speeds. If repetitions are greater than 1 the source
variables must be arrays containing elements for all repetitions.
DataType
A code to select the data storage format.

The number of samples per sub-interval calculation. Enter 0 for no sub-interval
calculations.
