7. Calibration
Recalibrate the CNR2 every two years, or as an alternative, by running a higher
standard next to it. Compare the pyranometers over a two-day period when the
days are clear. Compare the pyrgeometers during the night. Deviations of
more than 6% can be used to correct the calibration factors.
