LI200S PYRANOMETER 1. GENERAL This manual provides information for interfacing a CR10, 21X, and CR7 datalogger to a LI200S Pyranometer. An instruction manual provided by LI-COR contains the sensor calibration constant and serial number. Cross check this serial number against the serial number on your LI200S to ensure that the given calibration constant corresponds to your sensor. 3. MEASUREMENT INSTRUCTION 2.
LI200S PYRANOMETER EXAMPLE EXAMPLE -Sensor Calibration: Assume the sensor calibration is 87 microamps kW-1 m-2. The LI200S outputs amperage which is converted to voltage by 100 ohm shunt resistor in the cable, as shown in Figure 1. To convert the calibration from microamps to millivolts, multiply the calibration by 0.100. The example calibration changes to 8.7 mV kW-1 m-2. -Maximum Irradiance: A reasonable estimate of maximum irradiance at the earth’s surface is 1 kW m-2.
