gust meter reprogrammed

Richard, Fil, Jim W, Jim B, Dave

The voltage outputs from the gust meter when it was installed at EX yesterday did not look correct and did not correlate to wind conditions. Today Jim W brought the unit back to the shop and we tested it with a fan. There was some variation in voltage output but it did not look correct when referencing the manual. Jim Bconfigured the system for RS232 serial communications and logged into the unit. The serial readbacks for wind speed, azimuth and elevation looked correct. Jim reprogrammed the three voltage outputs to be Speed, Azimuth and Elevation. We then set the system back to analog voltage mode, and now the outputs vary by many volts and are V1=speed, V2=azimuth, V3=elevation. We suspect the system lost its programming at some time and was perhaps outputting U,V,W  analog voltages.

The unit is ready for re-install at EX.
