3. INSTALLATION
The HMP35C must be housed inside a radiation
shield when used in the field. The 41002
Radiation Shield (Figure 2) mounts to a
CM6/CM10 tripod or UT10 tower. The UT018
mounting arm and UT12VA Radiation Shield
mount to a UT30 tower (Figure 3).
A lead length of 6 feet allows the HMP35C to be
mounted at a 2 meter height on a CM6/CM10
tripod. Use a lead length of 9 feet for the UT10
tower or a UT30 tower respectively.
NOTE: The black outer jacket of the cable
is Santoprene
®
rubber. This compound was
chosen for its resistance to temperature
extremes, moisture, and UV degradation.
However, this jacket will support
combustion in air. It is rated as slow
burning when tested according to U.L. 94
H.B. and will pass FMVSS302. Local fire
codes may preclude its use inside buildings.
