    WindSonic1 default settings were changed in February 2013. WindSonic1 anemometers with newer settings will not work with older programs and Short Cut 3.0 or older. See Campbell Scientific factory default settings (p. 11) and Updating an older program for the new WindSonic1 settings (p.

  • Page 5: Initial Inspection

    Upon receipt of the WindSonic1, inspect the packaging and contents for damage. File damage claims with the shipping company. Immediately check package contents against the shipping documentation. Contact Campbell Scientific about any discrepancies. The model number and cable length are printed on a label at the connection end of the cable.
  • Page 6 3. In the Available Sensors and Devices box, type WindSonic1 or locate the sensor in the Sensors > Meteorological > Wind Speed & Direction folder. Double-click either WindSonic1 (RS-232 9.6K baud) or WindSonic1 (RS-232 38.4K baud); 9.6K baud is the factory-default setting.
  • Page 7 6. In Output Setup, type the scan rate, meaningful table names, and Data Output Storage Interval. Click Next. 7. Select the measurement and its associated output option. 8. Click Finish and save the program. Send the program to the data logger if the data logger is connected to the computer.

  • Page 8: Overview

    The WindSonic1 includes a user-specified cable to interface to a Campbell Scientific data logger. A serial cable (WINDSONICRCBL-L) is available for interfacing a WindSonic1 to a computer running the manufacturer’s computer support software. The cable and software are used during troubleshooting or to change settings for a specific application.

    Serial/power reference Black Shield Clear U and C terminals are automatically configured by the measurement instruction for Campbell Scientific CR6 data logger. NOTE: The maximum cable length depends on the baud rate, the nominal resistance of the wire, the capacitance between conductors, and the capacitance between the conductors and shield.

  • Page 17: Long Cables

    8.4 Long cables Communications between the WindSonic1 and the data logger will most likely fail if its cable is extended beyond 15 m (50 ft). Digital data transfer eliminates offset errors due to cable lengths. However, digital communications can break down when cables are too long, resulting in either no response from the sensor or corrupted readings.

  • Page 18: Maintenance

    If the WindSonic1 is damaged, fails to output data, or sends a nonzero status number (Table 9-1 (p. 14)), return it to Campbell Scientific for repair (see Assistance). 10. Siting references The following references give detailed information on siting wind direction and wind speed sensors.

  • Page 19: Appendix A. Importing Short Cut Code Into Crbasic Editor

    Appendix A. Importing Short Cut code into CRBasic Editor Short Cut creates a .DEF file that contains wiring information and a program file that can be imported into the CRBasic Editor. By default, these files reside in the C:\campbellsci\SCWin folder. Import Short Cut program file and wiring information into CRBasic Editor: 1.

  • Page 20: Appendix B. Determining True North And Sensor Orientation

    Appendix B. Determining True North and sensor orientation The orientation of the WindSonic1 north arrow markers is found by reading a magnetic compass and applying the site-specific correction for magnetic declination; where the magnetic declination is the number of degrees between true north and magnetic north. Obtain the magnetic declination for a specific site from a USGS map, local airport, or through a NOAA web calculator (Online magnetic declination calculator...
  • Page 21 For example, the declination for Longmont, CO (10 June 2006) is 9.67°, thus True North is 360° – 9.67°, or 350.33° as read on a compass. Likewise, the declination for McHenry, IL (10 June 2006) is –2.68°, and True North is 0° – (–2.68°), or 2.68° as read on a compass. FIGURE B-2.
