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 o f day, at any time of year, from obstructions such as trees, buildings

or the mast or structure on which it is mounted. In t he northern hemi sp here the

instrument is normally oriented towards the South to avoid potential problems

from shadin g.

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.
