Frequently Asked Questions FAQs

Frequently Asked Questions: 05103-L


  1. What is the procedure for orienting my wind sensor to the cardinal directions so that the wind direction readings are correct?

    Orientation of the wind direction sensor is done after the datalogger has been programmed, and the location of True North has been determined. True North is usually found by reading a magnetic compass and applying the correction for magnetic declination*; where magnetic declination is the number of degrees between True North and Magnetic North. Magnetic declination for a specific site can be obtained from a USFA map, local airport, or through a computer service.

    For additional information, please refer to section 4 in our tripods manual.



  2. If I replace an existing wind set with the wind monitor will I have to change more than the multiplier and offset in the datalogger program?

    The measurement instructions will likely remain the same, but in addition to the multiplier and offset, the type of pulse may change for the wind speed and the excitation voltage may change for the wind direction. The manual easily explains how the logger needs to be programmed.



  3. Can the wind monitor be used without your datalogger?

    Yes, but some electronic measurement, display, or recording device will be needed. A schematic for the wind monitor may be found in Appendix B of the manual. R.M. Young company at YoungUSA.com offers several display devices.




  4. We have a RM Young marine anemometer with a cable that is about 13' long. We would like to extend the cable another 20 feet or so. Do you sell a separate extension cable for the anemometer?

    We do not sell an extension cable. We do sell a replacement cable which is CSI model number 05106CBL-L that can be built to the desired length. This replacement cable has a connector that mates with the connector at the end of the 3 foot cable attached to the 05106 Marine Wind Monitor.




  5. What is the power consumption (mA) of the 05103, 05305, and 05106 anemometers?

    The short answer is less than 0.01 mA. The wind speed signal requires no power. The wind direction portion of the sensor only uses a maximum of 0.5 mA when excited with 5 Vdc, and then it is only on for 0.016 sec every measurement. When the wind direction is measured every second (typical), then the average current drain is less than 0.01 mA.
