3. Installation
The CS500 must be housed inside a solar radiation shield when used in the
field. The 41303 6-Plate Radiation Shield (Figure 1) mounts to a CM6/CM10
tripod or UT10 tower. The CS500 is held within the 41301 by a mounting
clamp (Figure 2).
The 41003 10-Plate Radiation Shield (Figure 3) mounts to a CM6/CM10
tripod. The UT12VA 12-Plate Radiation Shield mounts to a UT10 or UT30
tower with the UT018 horizontal mounting arm.
