    Voorbeeldzinnen

    1. In some types of opacimeter the gas between the light source and the photoelectric cell, or between transparent parts protecting the source and the photoelectric cell, is not of constant opacity.
    2. The construction of the electrical circuit, including the indicating dial, shall be such that the current output from the photoelectric cell is a linear function of the intensity of the light received over the operating-temperature range of the photoelectric cell.
    3. The check consists in verifying that this value does not differ by more than 0,05 m-1 from that read on the opacimeter indicating dial when the screen is introduced between the source of light and the photoelectric cell.
    4. The response time of the electrical measuring circuit, being the time necessary for the indicating dial to reach 90 % of full-scale deflection on insertion of a screen fully obscuring the photoelectric cell, shall be 0,9 to 1,1 seconds.
