INSTALLATION
Before installing the pyranometer, refill the cartridge containing silica-gel crystals. Sil-
ica gel absorbs humidity in the dome chamber and prevents, in particular climatic
conditions, condensation on the internal walls of the domes and measurement altera-
tion.
Do not touch the silica gel crystals with your hands while refilling the cartridge. Carry
out the following instructions in an environment as drier as possible:
1.
Loosen the three screws that fix the white shade disk.
2.
Unscrew the silica gel cartridge using a coin.
3.
Remove the cartridge perforated cap.
4.
Open the sachet containing silica gel (supplied with the pyranometer).
5.
Fill the cartridge with the silica gel crystals.
6.
Close the cartridge with its own cap, paying attention that the sealing O-ring be
properly positioned.
7.
Screw the cartridge to the pyranometer body using a coin.
8.
Check that the cartridge is screwed tightly (if not, silica gel life will be reduced).
9.
Position the shade disk and screw it with the screws.
10.
The pyranometer is ready for use.
The figure below shows the operations necessary to fill the cartridge with the silica gel
crystals.
