2.2.3 CM225 Pyranometer Stand 
The CM225 Pyranometer stand is used to mount the LI200X, LI190SB, 
CS300, CMP3, and LP02 solar radiation sensors to either a tower leg, mast, or 
crossarm. 
1.  If using a CS300, LI200X, or LI190SB, mount the leveling base to the 
CM225. The 18356 leveling base supports the CM300 pyranometer and 
the LI2003S leveling base supports the LI200X and LI190SB probes (see 
Figure 2.2-4). Both leveling bases use a bubble level and three adjustable 
leveling screws to level the sensor. The CMP3 and LP02 pyranometers 
include their own bubble level and leveling screws allowing them to attach 
directly to the CM225. 
2.  Mount the sensor to the leveling base or CM225. 
3.  Attach the CM225 to a tower leg, mast, or CM200-series crossarm. If 
attaching to a tower leg or mast, place the CM225’s u-bolt in the side 
holes (Figure 2.2-5). If attaching to a crossarm, place the CM225’s 
bottom holes (Figure 2.2-4).
