SP Lite2 Silicon Pyranometer

3. Installing the SP Lite2

The SP Lite2 with leveling instrument are attached to a tripod or tower using

one of two mounting configurations (see Figures 6).

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 Lite2 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.

FIGURE 6: SP Lite2 Mounting Configuration

Mount the sensor on the mounting arm at a height of at least 1.5 m above the

ground surface to minimize shading effects. The SP Lite2 has a built-in bubble

level should be used to level the SP Lite2 once mounted to the 015 ARM.

Mount and adjust the SP Lite2 as follows:
