    CS300 and CS301 Pyranometers Introduction The CS300 and CS301 measure total sun and sky solar radiation for solar, agricultural, meteorological, and hydrological applications. Their spectral range of 360 to 1120 nanometers encompasses most of the shortwave radiation that reaches the Earth surface. These pyranometers connect directly to our dataloggers.
  • Page 12 CS300 and CS301 Pyranometers The following procedure also describes programming with Short Cut. Open Short Cut and click Create New Program. Double-click the datalogger model. In the Available Sensors and Devices box, type CS301. Also locate the sensor in the Sensors | Meteorological | Solar Radiation folder. Double- click CS301 Pyranometer.
  • Page 13 CS300 and CS301 Pyranometers In Output Setup, type the scan rate, meaningful table names, and the Data Output Storage Interval. Select the measurement and its associated output options. Click Finish and save the program. Send the program to the datalogger if the datalogger is connected to the computer.

  • Page 14: Overview

    The resistance of the potentiometer is adjusted when the sensors are calibrated so that all sensors have the same output sensitivity. The CS300 and CS301 are calibrated against a Kipp and Zonen CM21 under natural sunlight to accurately measure sun plus sky radiation (360 to 1120 nm).
