LI200X Pyranometer 

2.  Place the LI200X in the center of the LI2003S base/leveling fixture. 

 

 

3.  Loosely mount the LI2003S base/leveling fixture on the 015ARM.  Do not 

fully tighten the three mounting screws.  
 
 
 

 

4.  Turn the leveling screws as required to bring the bubble of the bubble level 

within the ring.  

5.  Tighten the mounting screws to secure the assembly in its final position.  

Check that the pyranometer is still correctly leveled and adjust as 
necessary.  

6.  Route the sensor cable along the underside of the 015ARM’s arm to the 

tripod/tower, and to the instrument enclosure. 

7.  Secure the cable to the mounting arm and mast using cable ties. 

8.  Remove the red cap after installing the sensor.  Save this cap for shipping 

or storing the sensor.
