CS300 Pyranometer 1. Introduction The CS300, manufactured by Apogee Instruments, measures total sun and sky solar radiation for solar, agricultural, meteorological, and hydrological applications. Its spectral range of 360 to 1120 nanometers encompasses most of the shortwave radiation that reaches the Earth’s surface. This pyranometer connects directly to our dataloggers. Its output can be measured by all of our dataloggers. 2. 3.
CS300 Pyranometer 2 2. The Short Cut installation should place a Short Cut icon on the desktop of your computer. To open Short Cut, click on this icon. 3. When Short Cut opens, select New Program. 4. Select Datalogger Model and Scan Interval (default of 5 seconds is OK for most applications). Click Next.
CS300 Pyranometer 5. Under the Available Sensors and Devices list, select Sensors | Meteorological | Solar Radiation folder. Select CS300 Pyranometer. Click to move the selection to the Selected device window. Default units are kW/m2 for flux density units and mJ/ m2 for total flux. These can be changed by clicking the Flux Density and Total Flux boxes and selecting different values. 6.
CS300 Pyranometer 5. 7. Select any other sensors you have, then finish the remaining Short Cut steps to complete the program. The remaining steps are outlined in Short Cut Help, which is accessed by clicking on Help | Contents | Programming Steps. 8. If LoggerNet, PC400, RTDAQ, or PC200W is running on your PC, and the PC to datalogger connection is active, you can click Finish in Short Cut and you will be prompted to send the program just created to the datalogger. 9.

Loosely mount the 18356 base/leveling fixture on the CM225. Do not fully tighten the three mounting screws. Holes for Mounting Screws Leveling Screw Mounting Screw Bubble Level 5. Turn the leveling screws as required to bring the bubble of the bubble level within the ring. 6. Tighten the mounting screws to secure the assembly in its final position.
CS300 Pyranometer 7. Route the sensor cable along the underside of the crossarm to the tripod/tower, and to the instrument enclosure. 8. Secure the cable to the crossarm and mast using cable ties. Cable Tie 9. Remove the green cap after installing the sensor. Save this cap for shipping or storing the sensor. 1. Secure the 015ARM to the mast by tightening the U-bolt nuts. 7.2.2.2 015ARM U-bolt Nuts 015ARM 2. Place the CS300 in the center of the 18356 base/leveling fixture.

CS300 Pyranometer 8. Maintenance and Calibration On a monthly basis the level of the pyranometer should be checked. Any dust or debris on the sensor head should be removed. The debris can be removed with a blast of compressed air or with a soft bristle, camel hair brush. CAUTION Handle the sensor carefully when cleaning. Be careful not to scratch the surface of the sensor. Recalibrate the CS300 every three years. Obtain an RMA number before returning the CS300 to Campbell Scientific, Inc.
Appendix A. Importing Short Cut Code Into CRBasic or Edlog Editor This tutorial shows: • • How to import a Short Cut program into a program editor for additional refinement How to import a wiring diagram from Short Cut into the comments of a custom program A.1 Importing Short Cut Code into a Program Editor Short Cut creates files that can be imported into either CRBasic Editor or Edlog program editor.
Appendix A. Importing Short Cut Code Into CRBasic or Edlog Editor NOTE Once the file is edited with CRBasic Editor, Short Cut can no longer be used to edit the datalogger program. Change the name of the program file or move it, or Short Cut may overwrite it next time it is used. 5. The program can now be edited, saved, and sent to the datalogger. 6. Import wiring information to the program by opening the associated .DEF file.
Appendix B. Example Programs The following programs measure the CS300 every 10 s and convert the millivolt output to Wm–2 and MJm–2. Both programs output an hourly average flux (Wm–2), and a daily total flux density (MJm–2). Negative values are set to zero before being processed. Wiring for the examples is given in TABLE B-1.
