3 INSTALLATION
Before installing the pyrheliometer, refill the cartridge containing silica-gel crystals.
Silica gel absorbs humidity inside the instrument and prevents, in particular climatic
conditions, condensation on the internal wall of the quartz window and measurement
alteration.
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.
Unscrew the silica gel cartridge using a coin.
2. Remove the cartridge perforated cap.
3. Open the sachet containing silica gel (supplied with the pyrheliometer).
4. Fill the cartridge with the silica gel crystals.
5. Close the cartridge with its own cap, paying attention that the sealing O-ring be
properly positioned.
6. Screw the cartridge to the pyrheliometer body using a coin.
7. Check that the cartridge is screwed tightly (if not, silica gel life will be reduced).
8. The pyrheliometer is ready for use.
The figure below shows the operations necessary to fill the cartridge with the silica gel
crystals.
