10 MAINTENANCE
In order to grant measurements high accuracy, it is important to keep the outer glass
dome clean. Consequently, the more the dome will be kept clean, the more measure-
ments will be accurate.
You can wash it using water and standard papers for lens. If necessary, use pure
ETHYL alcohol. After using alcohol, clean again the dome with water only.
To minimize condensation and keep measurements accurate, desiccant silica-gel is
provided inside the pyranometer base to absorb moisture. The silica-gel life is at least
4 years and can be replaced by the user.
To replace the silica-gel, unscrew the 4 screws that fix the base to the main body of
the pyranometer; remove the silica-gel sachet and insert a new sachet, then screw
the pyranometer base back on.
Warning: the silica-gel replacement must be done in an ESD-safe environment.
To exploit all the pyranometer features, it is highly recommended that the calibration
be checked annually.
The pyranometer provides the operating time in days since first and last power on,
and allows time alarm thresholds to be set to alert the user of the need for periodic
verification or maintenance. The exceeding of thresholds can be read via Modbus "Dis-
crete inputs" or DATAsense software. The thresholds can be set via Modbus "Holding
registers", WAL1/WAL2 serial commands, or DATAsense software.
