Be careful not to scratch the surface of the sensor. Recalibrate the LI200X every two years. Obtain an RMA number before returning the LI200X to Campbell Scientific, Inc. for recalibration. 6. CALIBRATION LI200X pyranometers output a current that is proportional to the incoming solar radiation. -

A.1 LI200S PYRANOMETER LI200S pyranometers have a 100 ohm shunt resistor built into the cable. They can be directly measured by Campbell Scientific dataloggers. The input range and multipliers vary from one pyranometer to another. See Sections A.3 and A.4 for calculating the proper input range and multiplier. -
