Page 9: Introduction
Upon receipt of the LI200X, inspect the packaging and contents for damage. File damage claims with the shipping company. Quickstart Short Cut is an easy way to program your datalogger to measure the LI200X and assign datalogger wiring terminals. The following procedure shows using Short Cut to program the LI200X. - Page 10 LI200X Pyranometer 2. The Short Cut installation should place a shortcut icon on the desktop of your computer. To open Short Cut, click on this icon. 3. When Short Cut opens, select New Program. 4. Select Datalogger Model and Scan Interval (default of 5 seconds is OK...
- Page 11 LI200X Pyranometer 5. Under the Available Sensors and Devices list, select the Sensors | Solar Radiation folder. Select LI200X Pyranometer. Click to move the selection to the Selected device window. The flux density defaults to kW/m^2 and the total flux defaults to MJ/m^2. This can be changed by clicking the Flux Density or Total Flux box and selecting one of the other options.

Page 14: Installation
Section 4, Quickstart, for a Short Cut tutorial. Siting The LI200X 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. - Page 15 2. Place the CM225’s U-bolt in the bottom holes and secure the CM225 to the crossarm by tightening the U-bolt nuts. CM225 Stand U-bolt Nuts CM200-Series Crossarm 3.

Page 18: Wiring
LI200X Pyranometer Wiring A schematic diagram of the LI200X is shown in FIGURE 7-1. Connections to Campbell Scientific dataloggers are given in TABLE 7-1. When Short Cut software is used to create the datalogger program, the sensor should be wired to the channels shown in the wiring diagram created by Short Cut. -
Page 19: Total Solar Radiation
Edlog dataloggers are provided at www.campbellsci.com/old-manuals. –2 –1 Output from the LI200X is 0.2 kW m , which is measured by the datalogger using the VoltDiff CRBasic instruction. CRBasic is included in PC400 and LoggerNet datalogger support software. -
Page 20: Calibration
Calibration LI200X pyranometers output a current that is proportional to the incoming solar radiation. Each LI200X has a unique calibration factor. A variable shunt resistor in the cable converts the current to the voltage measured by the datalogger. Campbell Scientific sets the shunt resistor so that the pyranometer –1... -

Appendix A. Importing Short Cut Code This tutorial shows: • How to import a Short Cut program into a program editor for additional refinement. • How to import a wiring diagram from Short Cut into the comments of a custom program. A.1 Importing Short Cut Code into a Program Editor Short Cut creates files that can be imported into either CRBasic Editor or Edlog program editor. - Page 22 Appendix A. Importing Short Cut Code mark) begins each line. This character instructs the datalogger compiler to ignore the line when compiling the datalogger code.

C.2 Unmodified Pyranometers Pyranometers that do not have variable or fixed shunt resistors built into the cable can still be measured by Campbell Scientific dataloggers. This is done by wiring in a 100 Ω shunt resistor directly onto the datalogger wiring panel. -
Page 26: Input Range
Appendix C. LI200S Pyranometer C.3 Input Range The following is an example of how to determine the optimum input range for a given sensor calibration and maximum expected irradiance. This is an example only. Your values will be different. This example uses the calibration provided by LI-COR, Inc.
