To estimate accurately energetic luminance (EL) of objects for determination of their optical properties it is necessary to know the error of measurement mean -- that is radiometer error. Using the multichannel radiometers with several spectral ranges allows us to increase the reliability of the results, but it creates some difficulties during the graduating with external reference radiators. With large distance between the spread of spectrum bands, for example from the middle wavelengths to the long wavelength, the requirements to a range and stability of EL reproduction by external reference radiators become individual for every channel.
