According to theory and methods of testing meter:
1. Illumination of the testing principle
Illumination is subject to acceptance of the luminous flux according to the plane of the surface density. Illumination meter is used to measure the illuminated surface of the instrument illumination, is light measurement instrument using one of the most frequently.
2. The structural principle according to meters
According to meters from the optical head (also known by the optical probe, including the receiver, V (λ) of the filter, cosine modifier), and reading display of two parts.
