RECALIBRATION
 
The output of all radiation sensors tends
to decrease over time as the detector
ages. Our measurements indicate that
quantum sensors under continuous outdoor
use should be recalibrated every 2 years. Sensors exposed to less than constant
solar radiation, such as a meter stored
indoors, can be recalibrated every 3 years.  Apogee also offers recalibration of LI-COR Quantum Sensors.

Do not attempt recalibration without a
radiation standard.
