These steps are indicated below, along with their page num-bers for easy reference:3Assemble and test the station, page 33Detach the extension tube, page 33Attach the anemometer, page 33Attach the wind cups, page 33Snip the cable tie in the rain collector, page 43Apply power to the console, page 43Apply power to the sensor array, page 63Check that the console is working properly, page 73Choose locations for the sensor array and console, page 73Test the proposed locations, page 83Set dip switches to control ID code and operating mode, page 93Mount the sensor array, page 113Secure the sensor array and re-apply power, page 133Mount the console, page 13If, once installed, you encounter any problems with the station, please refer to the troubleshooting guide on page 14.Page 2Wireless Weather StationAssembling the Station Page 3Page 4Wireless Weather StationAssembling the Station Page 5Page 6Wireless Weather Station8.Check all of the readings on your display to be sure they appear correctly (i.e., not“dashed out”).Consult your Monitor or Wizard owner’s manual for instructions on dis-playing the various readings. Spin the wind cups, move the wind vane, and tip the rain bucket to verify wind speed and direction and rainfall readings.Note that some readings (e.g., wind direction, barometer, and 0.2 mm raincollectors) must be calibrated in order to read correctly; calibration instruc-tions are contained in the Monitor or Wizard owner’s manual.If the console is having problems reading the outdoor sensors, consult thetroubleshooting guide at the end of this manual. If the problem is with theinside temperature, inside humidity or barometer, consult the Monitor orWizard owner’s manual.9.Re-attach the rain collector cone and lay the debris screen “feet-down” over thecone’s funnel hole.C HOOSING L OCATIONS FOR THE S ENSOR A RRAY AND C ONSOLEThe range of the radio transmission depends on several factors. Try to posi-tion the sensor array and console as close together as possible for best results.Typical maximum ranges:3Line of Sight: 400 feet (120 m)3Through Walls and Ceilings: 100 to 200 feet (30 to 60 m)3Through Trees and Foliage: 100 to 200 feet (30 to 60 m)As you position your sensor array, try to avoid possible obstructions of rain and wind—look out for trees and nearby buildings. For roof mounting, and for ease of installation in other locations, we recommend using the optionalMounting Tripod (contact Davis for more information).As you position your console, be aware of possible interference from cordless phones and other items. To prevent interference, maintain a distance of 10 feet between the console and the cordless phone (handset and base). Also, for best reception, avoid positioning the console near large metallic surfaces (e.g., most refrigerator surfaces).Choosing Locations for the Sensor Array and Console Page 7Page 8Wireless Weather StationDip Switch Settings Page 9Page 10Wireless Weather StationMounting the Sensor Array Page 11Page 12Wireless Weather StationMounting the Console Page 13T ROUBLESHOOTINGPlease check the troubleshooters listed below if you experience a problem with your station. Then, if you still are unable to solve the problem, we encourage you to call the factory at (510) 732-7814 for assistance. Please do not return your unit for repair without prior authorization.3Console is receiving erratic data from the sensor arrayEnable the “Test" mode on the sensor array (see “Testing Proposed Loca-tions” on page 8). If two beeps or more are heard in a 2.5-second interval,then another Davis wireless system may be operating nearby on the same ID (or a cordless phone may be operating within 10 feet of the receiver). Trychanging to a different ID code on both the console and the sensor array (or try moving the phone). Repower the console to activate the new ID code.3Console is not receiving any data from the sensor arrayThe sensor array and the console may be too far apart, or something in their path may be interfering, such as foliage, furnishings or cordless phones.Enable Test Mode on sensor array to see if it is receiving data (see “TestingProposed Locations” on page 8). Try moving the console closer to the sensor array or vice versa; or eliminating possible path interferences.3Console is emitting beepsIf you hear single beeps, ﬂip dip switch #4 to turn off Test Mode in both thetransmitter and receiver.If you hear a double beep, the SensorLink Receiver in the console is not receiv-ing data. This occurs when the SensorLink Receiver has not received datafor 30 minutes. Try moving the console closer to the sensor array or viceversa; or eliminating possible path interferences.If you hear a triple beep, the SensorLink Transmitter in the sensor array isextremely low on power—replace battery immediately.3Data from the optional WeatherLink program shows temperature, humidity, or wind values that were constant over some periodThe SensorLink Receiver in the console did not receive new data during this period and passed the last good data to the WeatherLink. Try moving theconsole closer to the sensor array or vice versa; or eliminating possible path interferences.3Battery(ies) are not lasting the expected 6 months (for 1 battery) or 1 year (for 2) Make sure dip switch #4 in the transmitter is set to OFF to prevent the LEDfrom ﬂashing unnecessarily when not testing (see “Testing Proposed Loca-tions” on page 8). If you are using two batteries, also make sure that bothare fresh when installed.3Console is not registering any rainfall.Double check that you have cut the cable tie that secures the rain bucketduring shipping. See step 4 on page 4 for instructions.3Console does not register wind direction correctlyCheck that you have mounted the sensor array with the anemometer arm Page 14Wireless Weather Stationpointing south. Or, if your station points in a direction other than south,check that you have recalibrated the weather vane correctly. See the “Install-ing the Anemometer” section of your owner’s manual for instructions.3Console locks upInsufﬁcient power during power up or a power surge may cause the console to lock up. If this occurs, remove all power by disconnecting any batterybackup and the AC/DC power cord. Wait for 1 minute with all of the power removed. Then re-connect the AC/DC power cord and listen for 3 beepswithin 20 seconds (or, with the optional WeatherLink, 4 beeps within 30 sec-onds). Once you have received the ﬁnal beep, install a fresh backup battery, if desired, and put the console back into service.S PECIFICATIONSSensorLink ReceiverReceive frequency: 916.5 MHzID codes: 8 user-selectableTemperature range: 0 to 60 °CUpdate intervalWind speed: 2.5 secondsWind Direction: 2.5 secondsOutside Temperature: 16 secondsOutside Humidity: 1 minuteRain: 10 seconds (rain counts are saved in the transmitter until successfully received by the console)SensorLink TransmitterTransmit frequency: 916.5 MHzID codes: 8 user-selectableLicense: Low power (less than 1 mW), no license requiredSensor connections: Telephone modular for Anemometer, Temp/Hum Sensor, and Rain CollectorTemperature range: -40 to 60 °CPower Input OptionsBattery power: CR-123 3- volt lithium or equal; one or two cellsAC power adapter: Davis adapter or equal (5 to 10 VDC output @ 1mA)Solar Power Kit: Davis solar charger (Optional, product #7709.

HOBO水位水温计使用说明书(V3.7.8版本)

HOBO水位水温计使用说明书（一）HOBO水位计的构成：1）Water level logger（水位计）and End cap（水位计帽）水位计（Water level logger）是银白色的金属体，End cap是与水位计相连的黑色螺旋帽。

2）Coupler（转接口）出厂时，厂家提供不同型号的转接口，依据水位计的型号选择合适的转接口。

3）Base station（数据传输底座）Base station（数据传输底座）用于水位计启动（Launch）、参数设定、数据下载（Readout）Base station与转接口直接相连，转接口与水位计相连。

然后插入电脑中USB接口，即可进行启动、参数设置、数据下载。

（二）水位计的使用1）水位计的启动打开HOBOware Pro程序，弹出程序主界面。

点击Launch快捷菜单（鼠标所在位置），如果是第一次使用该程序，可能提示是否升级，点击否。

查看水位计状态在弹出的selcet device窗口，可以看到该水位计的序列号，例如：S/N：1136880。

点击OK。

屏幕出现Launch Logger 窗口，包含几个选项：Channel to logger；Logging Interval；Launch option。

Channel to logger------选择通道，包含压力、温度、电池电压；Logging Interval----选择采样间隔；Launch option------启动时间，可以选择现在启动、滞后启动等选项。

依据实际需求，进行设置。

然后点击Launch按钮。

屏幕很快闪过一个窗口，提示水位计启动过程中不可以将水位计从转接口中拔出。

经过如上操作，水位计就被启动了。

设置记录时间间隔。

给本次记录数据文件定名，设置记录时间间隔和开始记录时间。

设置开始记录时间，最好选择日期/时间（将会延迟到整点启动），从最近的一个整时间刻度开始，否则若选择从“现在”开始记录，记录时间常为**分**秒，很不规整，还需另行处理数据。
