1. 如果风监视器上的速度指示器停止工作，是否可以更换零件，或者需要更换整个单元？

   这取决于破碎的东西。通常，Campbell Scientific可以修复该单元，并且用户不必购买新设备。

2. 如果现有的风集替换为风监视器（05103-L，05103-45-L，05106-L，05305-L），那么在数据记录程序程序中必须更改乘数和偏移量是否还要多吗？

   测量说明可能会保持不变。但是，除了乘数和偏移量外，风速可能会改变脉冲的类型，并且激发电压可能会在风向方向变化。有关如何对数据记录器进行编程的说明，请参见这说明手册。

3. 05103-L和05103-45-L会产生相同的输出吗？

   是的。

4. 是否可以从05103-L的风速和方向获得4到20 mA的输出？

   是的，但这不是坎贝尔科学提供的标准产品。但是，我们可以从制造商（R. M. Young）订购一个。

5. What is the power consumption (mA) of the 05103-L, 05103-45-L, 05305-L, and 05106-L 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 s for every measurement. When the wind direction is measured every second (typical), the average current drain is less than 0.01 mA.

6. Can the output of a wind monitor (05103-L, 05103-45-L, 05106-L, or 05305-L) be changed to analog dc voltage?

   不。

7. What is the procedure for orienting a wind monitor (05103-L, 05103-45-L, 05305-L, or 05106-L) to the cardinal directions so that the wind direction readings are correct?

   Orientation of the wind monitor is done after the data logger 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.

8. What are the different cable length choices available for Campbell Scientific sensors?

   大多数坎贝尔科学传感器都可以作为–L提供，该传感器表示用户指定的电缆长度。如果将传感器列为–LX模型（其中“ X”是其他字符），则传感器的电缆具有用户指定的长度，但它用特定的连接器终止了独特系统：

   • An –LC model has a user-specified cable length for connection to an ET107, CS110, or retired Metdata1.
   • An –LQ model has a user-specified cable length for connection to a RAWS-P weather station.

   如果传感器在主型号之后没有–L或其他-LX名称，则传感器具有设置的电缆长度。电缆长度在产品订购信息中的描述字段末尾列出。例如，034B-ET型号的描述说明“遇到了一个为ET站的一组，67英寸电缆”。具有固定电缆长度的产品，默认情况下，带辫子。

   If a cable terminates with a special connector for a unique system, the end of the model number designates which system. For example, the 034B-ET model designates the sensor as a 034B for an ET107 system.

   • –ET models terminate with the connector for an ET107 weather station.
   • –ETM models terminate with the connector for an ET107 weather station, but they also include a special system mounting, which is often convenient when purchasing a replacement part.
   • –QD models terminate with the connector for a RAWS-F Quick Deployment Station.
   • –PW models terminate with the connector for a PWENC or pre-wired system.
9. Where are the available cable termination options listed for a particular sensor?

   Not every sensor has different cable termination options. The options available for a particular sensor can be checked by looking in two places in the Ordering information area of the sensor product page:

   • Model number
   • Cable Termination Options list

   If a sensor is offered in an –ET, –ETM, –LC, –LQ, or –QD version, that option’s availability is reflected in the sensor model number. For example, the 034B is offered as the 034B-ET, 034B-ETM, 034B-LC, 034B-LQ, and 034B-QD.

   All of the other cable termination options, if available, are listed on the Ordering information area of the sensor product page under “Cable Termination Options.” For example, the 034B-L Wind Set is offered with the –CWS, –PT, and –PW options, as shown in the Ordering information area of the 034B-L product page.

   笔记：由于通常将较新的产品添加到我们的库存中，因此我们将在单个传感器模型下列出多个电缆终止选项，而不是创建多个模型号。例如，HC2S3-L具有将其连接到CS110而不是提供HC2S3-LC模型的–C电缆终止选项。

10. What is the maximum recommended cable length between a 05103-L Wind Monitor and a data system/display?

    R. M. Young, the manufacturer of this sensor, recommends a maximum cable length of 300 m (984.25 ft) between the wind monitor and a data system/display. For longer cable runs, either the Line Driver (4 to 20 mA outputs) or the Serial Interface (RS-485) is suggested.
