7.2.2 Wind Speed Measurements - Execution Interval Averaging
The INT8 is used to make 1 second averages of frequencies from 6 RM Young
Wind Monitors. Frequencies are converted to wind speed in m/s, and place in
Input Locations 1 - 6. Wind directions are then measured, scaled, and placed
in Input Locations 7-12. Programming does not output the data to the
dataloggers' Final Storage.
Note that wind speeds of less than 0.2 m/s, corresponding to 2 Hz, will read 0
if a cycle of the Wind Monitor does not get completed within the 1 second
execution interval.
