The lightsourceand the receiver shallbe placedexternally in the centre of both windows in the two opposite walls of the cubewithout making physical contact. The lightbeam shalltraverse the cube through the glasswindow

The photocell shall be mounted at the end of 150 mm 10 mm tube with adust protection window at the otherend.
40、The inside of the tube shall be matt black to preventreflections. Thephotocell shallbeconnected to apotentiometric recorder to produce alinearproportional output. The cell shallberesistance-loaded to operate in its linear range and theinput impedance of the recorder shall be at least 104 times great

42、 NOTE 1 Periodically, for example at the beginning of atest series, the performance of the photocell should beverified by placing standardneutral density filters in the light beam. It is essential that these filters cover the entireoptical port of the photocell and the values oftransmittancemeasured
