3 INSTALLATION
When installing the radiometer you must consider:
1. The radiometer should be installed as high as
possible to minimize obscuration by trees, buildings,
etc. This includes the obscuration of the indirect,
scattered radiation coming from the whole upper
hemisphere. A large portion of the received UV
radiation does not reach the radiometer directly
from the sun, but is scattered by molecules and
particles. Ideally the view should be clear to the
horizon in all directions.
2. The radiometer should be carefully levelled in the
horizontal plane. Use the built-in spirit level to find
the correct position.
3. The installation of the radiometer must ensure
natural ventilation to reduce heating of the housing
caused by solar radiation and electrical power
dissipation. If the housing becomes too hot,
damage may occur.
