6.4.2 Annual maintenance
Ideally, the annual m aintenance should take less than one day to complete if a team of workers is
present. Although unlikely, it would be best done while the sun is below the horizon.
(1) Calibration of the cavity radiometer (see Section 8.2.1).
(2) All field support assemblies should be checked for level and structural integrity.
(3) All bolts should be loosened, lubricated and tightened. This preventative m aintenance is
especially important in areas of harsh climate where corrosion may occur.
(4) Fans used in ventilated housings should be lubricated or replaced (depending on the type
of system in use).
(5) Calibration of the digital voltm eter (or equivalent) used in the data acquisition system. Because
of the complex nature of system testing and calibration (it is not just placing a known source
on the input terminals) this procedure should only be done by qualified personnel, either
associated with the metrology laboratory of the institution operating the BSRN station or the
manufacturer. The calibration should be traceable to a national standards institute. It is
recomm ended that one or more spare units be obtained so that during a calibration a newly-
calibrated spare unit can replace the unit being calibrated.
