    The model number and cable length are printed on a label at the connection end of the cable. Check this information against the shipping documents to ensure the expected product and cable length are received. The sensor is shipped with the cup wheel unattached to the anemometer shaft.

    This is a special version of the 03102 built for Campbell Scientific by R. M. Young that has shielded bearings rather than sealed bearings. The shielded bearings provide a lower starting threshold than sealed bearings.

    7.2 Programming Short Cut is the best source for up-to-date data logger programming code. If your data acquisition requirements are simple and you are connecting the sensor to a pulse terminal, you can probably create and maintain a data logger program exclusively by using Short Cut. If your data acquisition needs are more complex, the files that Short Cut creates are a great source for programming code to start a new program or add to an existing custom program.

  • Page 14: Windvector Processing Instruction

    7.2.3 WindVector processing instruction WindVector output is used to process and store mean wind speed, unit vector mean wind direction, and standard deviation of the wind direction (optional) by using the measured wind speed and direction samples. 7.3 Siting Locate wind sensors away from obstructions such as trees or buildings. Generally, there should be a horizontal distance of at least ten times the height of the obstruction between the wind monitor and the obstruction.

If a pyranometer is also being mounted on the crossarm, orient the crossarm north-south with the Nu-Rail on the end farthest from the equator. Otherwise, the crossarm may be oriented north-south, east west, or any other angle desired.
