3. Installing the SP-LITE
The SP-LITE and PN 14282 base/leveling fixture are attached to a tripod or
tower using one of two mounting configurations (see Figures 6 - 7).
Mount the sensor on the mounting arm so that no shadow will be cast on it at
any time of day, at any time of year, from obstructions such as trees, buildings
or the mast or structure on which it is mounted. In the northern hemisphere the
instrument is normally oriented towards the South to avoid potential problems
from shading.
The SP-LITE will only perform to specification under clear-sky
conditions. It must not be mounted where it is subject to shade,
beneath structures or beneath a plant canopy.
