    CS300 Pyranometer 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.

  • Page 10: Quickstart

    CS300 Pyranometer QuickStart Short Cut is an easy way to program your datalogger to measure the CS300 and assign datalogger wiring terminals. Use the following procedure to get started. 1. Install Short Cut by clicking on the install file icon. Get the install file from either www.campbellsci.com, the ResourceDVD, or find it in...

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...

  • Page 12: Overview

    The resistance of the potentiometer is adjusted when the sensor is calibrated so that all sensors have the same output sensitivity. The CS300 is calibrated against a Kipp and Zonen CM21 under natural sunlight to accurately measure sun plus sky radiation (360 to 1120 nm). The CS300 should not be used under vegetation or artificial lights.

    (p. 2) Siting The CS300 should be mounted such that no shadows or reflections are cast on it by the tripod/tower or other sensors. The sensor should be mounted with the cable pointing towards the nearest magnetic pole. For example, in the Northern Hemisphere, point the cable toward the North Pole.

After pasting, edit the information such that a ' character (single quotation mark) begins each line. This character instructs the datalogger compiler to ignore the line when compiling the datalogger code.
