The radiometer must be mounted in an easy-to-reach location in order to clean the
dome regularly and carry out maintenance. At the same time, make sure that no
buildings, constructions, trees or obstructions exceed the horizontal plane where
the radiometer lies. If this is not possible, select a site where obstructions in the
path of the sun from sunrise to sunset do not exceed 5 degrees of elevation.
•
The radiometer must be located far from any kind of obstruction, which might re-
flect sunlight (or sun shadow) onto the radiometer itself.
•
For fixing, use the holes on the radiometer body (remove the shade disk to access
the holes and reposition it after mounting) or the suitable accessories (see the fig-
ures below). In order to allow an accurate horizontal positioning, the radiometer is
equipped with a levelling device: the adjustment is made by means of the two lev-
elling screws that allow adjusting the radiometer inclination. The mast height does
not exceed the radiometer plane to avoid measurement errors caused by any re-
flection or shadow of the mast itself.
•
It is preferably to thermally insulate the radiometer from its mounting bracket en-
suring, at the same time, a good electrical contact to ground.
