  Infratec™ 1241 Grain Analyzer 5.2.6 Use of the Aperture Kit (p/n 60023539) General The optical characteristics of each individual instrument are slightly different. Therefore it’s sometimes necessary to reduce the amount of light energy from the lamp onto the fibre bundle located just below the lamp. This describes the procedure to determine which aperture size to use and the way to fit it in the instrument.

• Page 142
  Infratec™ 1241 Grain Analyzer Procedure Aperture, Installation Switch off the instrument. Remove the screws securing the lamp cover and lift up the lamp and lamp holder assembly. Fig. 5:14 Inspect if an aperture already is fitted in the lamp housing. Usually not, which is the case in the picture below.
• Page 143
  Infratec™ 1241 Grain Analyzer Usually the high limit is exceeded as described in the previous section and then you need to install a suitable aperture. In such a case we recommend to select the 6.5 mm size aperture as your first choice. When fitting the aperture, great care have to be taken not to touch or damage the surface of the fiber bundle.
