The invention relates to a non-oriented electrical steel sheet, widely used as an iron core in electric devices, and to a method of manufacturing the same. These methods are continuous automated titration methods that use titration chemistries to measure the target analyte concentration in the process solution. The angled hole in the crank pin extends between the inner and outer surfaces, with the angled hole starting on the outer surface at a location along a distance L1 and extends to the inner surface exiting at a location inboard of the distance L1, the angled hole being linear along its length. Then the white signal component and the adjusted primary signal components will form a display signal for displaying brightness controlled images.
