Abstract
A method and apparatus that allows the adjustment of the intensity of the illumination source in a barcode reader, using the barcode reader as the measuring device, to give a predetermined amount of light from a known target. The adjustment of the intensity of the illumination source in the barcode reader compensates for the manufacturing tolerances of the barcode reader.
