  • Page 6: General Description

    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 (300 to 1100 nm). The CS300 should not be used under vegetation or artificial lights.

  • Page 7: Installation

    CS300 Pyranometer 3. Installation The CS300 should be mounted such that it is never shaded by the tripod/tower or other sensors. The sensor should be mounted with the cable pointing towards the nearest magnetic pole, e.g., in the Northern Hemisphere point the cable toward the North Pole.
