Page 7: Introduction
Safety Care should be taken when opening the shipping package to not damage or cut the cable jacket. If damage to the cable is suspected, consult with a Campbell Scientific support and implementation engineer. Opening the unit or breaking the security seal will void the warranty and the calibration. -
Page 8: Quickstart
4. QuickStart A video that describes data logger programming using Short Cut is available at: www.campbellsci.eu/videos/cr1000x-data logger-getting-started-program-part-3. Short Cut is an easy way to program your data logger to measure the sensor and assign data logger wiring terminals. Short Cut is available as a download on www.campbellsci.eu. It is included in installations of LoggerNet, RTDAQ, and PC400. - Page 9 4. Click the Wiring tab to see how the sensor is to be wired to the data logger. Click OK after wiring the sensor. 5. Repeat steps three and four for other sensors. 6. In Output Setup, type the scan rate, meaningful table names, and Data Output Storage Interval.

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. 9. If the sensor is connected to the data logger, check the output of the sensor in the data display in LoggerNet, RTDAQ, or PC400 to make sure it is making reasonable measurements. - Page 11 www.campbellsci.eu/metsens550 www.campbellsci.eu/metsens600 Operating temperature range: –40 to 70 °C Operating voltage: 5 to 30 VDC Typical current drain @ 12 VDC: 25 mA continuous high mode, 0.7 mA eco-power mode (1 hour polled) Table 5-1: Measurements, weight, and dimensions Model Measurements Weight Dimensions...

The RS-485 output can be directly read by a MeteoPV, CR6-series, CR1000X-series, or Modbus RTU RS-485 network. Other Campbell Scientific data loggers can use an MD485 multidrop interface to read the RS-485 output. Refer to the MD485 manual for information about using the MD485. -

(p. 14)). ModbusOption is an optional parameter register count (see Modbus measurements described in the CRBasic Editor Help. 6.2.2 SDI-12 programming SDI12Recorder() instruction is used to measure a MetSENS-series configured for SDI-12 SDI12Recorder() measurements. The instruction sends a request to the sensor to make a measurement and then retrieves the measurement from the sensor. -
Page 19: Siting Considerations For Wind Measurements
6.3 Siting considerations for wind measurements Locate the sensor away from obstructions such as trees and buildings. The horizontal distance from an obstruction should be at least ten times the height of the obstruction. If it is necessary to mount the sensor on the roof of a building, the height of the sensor above the roof, should be at least 1.5 times the height of the building. -

6. If measuring wind direction, ensure that the four notches on the sensor are aligned to the magnetic north (see www.geosats.com/magdecli.html www.ngdc.noaa.gov/geomag/declination.shtml 7.

7.3 Status codes NOTE: For all factory repairs, customers must get an RMA number. Customers must also properly fill out a “Declaration of Hazardous Material and Decontamination” form and comply with the requirements specified in it. Refer to the Assistance page at the back of this manual for more information. -
Page 26: 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 27: Appendix B. Sdi-12 Sensor Support
SDI-12, Serial Data Interface at 1200 baud, is a protocol developed to simplify sensor and data logger compatibility. Only three wires are necessary — serial data, ground, and 12 V. With unique addresses, multiple SDI-12 sensors can connect to a single SDI-12 terminal on a Campbell Scientific data logger. -

B.1.6 Start measurement commands (aM!) A measurement is initiated with the M! command. The response to each command has the form atttn<CR><LF>, where a = sensor address ttt = time, in seconds, until measurement data is available. When the data is ready, the sensor notifies the data logger, and the data logger begins issuing D commands. -

Page 32: Changing An Sdi-12 Address
SDI-12 sensor. The steps shown in Changing an SDI-12 address (p. 26) are used with most Campbell Scientific data loggers. B.2.1 Changing an SDI-12 address This example was done with a CR1000X, but the steps are only slightly different for CR6, CR3000, CR800-series, CR300-series, CR1000 data loggers. - Page 33 5. Click the Terminal tab. 6. Select All Caps Mode. 7. Press Enter until the data logger responds with the data logger (CR1000X>) prompt. 8. Type SDI12 and press Enter. 9. At the Select SDI12 Port prompt, type the number corresponding to the control port where the sensor is connected and press Enter.
- Page 34 11. To change the SDI-12 address, type aAb!, where a is the current address from the previous step and b is the new address. Press Enter. The sensor changes its address and responds with the new address. In the following example, the sensor address is changed from 0 to B. 12.
