Do not measure in high temperature and high humidity environment.
In using, the photodetector should be kept clean.
The reference position of the light source test is at the top of the spherical surface.
The sensitivity of the detector will be reduced by using conditions or time. It is recommended that you calibrate the meter regularly to maintain the basic accuracy.
