4.4 Adjustment of the measuring aperture 20 mil
The adjustment process for the aperture 20 mil is the same as that for the 6, 8 and 10 mil
apertures. The only difference is that the process is concluded with metric fine adjustment with the
larger EAN code (200%). The mean value and dark value must be taken from the 20 mil reference
test report. The sticker on the card only contains the values for the small EAN code.
