The intrinsic uncertainty is the error specified for the reference conditions.

5.2. Optical Specifications

The Model 1110 is a class C lightmeter per standard NF C-42-710. Its sensor is a silicon (Si) photodiode in which
the spectral response is corrected by an optical filter. The directional response is ensured by a diffusing lens.
