Abstract
Abstract This invention provides an inspection arrangement for a code symbol consisting of a plurality of spaced parallel bars of different widths and predetermined spacing, the inspection arrangement including a sheet having a plurality of spaced viewable areas which may be defined by the edges of windows in the sheet member. The windows have relatively wide portions which are the maximum width dimensions for the corresponding bars of the code symbol and relatively narrow portions at the minimum bar width dimensions. The inspection device is placed over the code symbol and positioned to determine if all of the bars can be made to fall entirely within their corresponding inspection windows. The device also is positioned to center the bars to ascertain if their dimensions are at least as wide as that of the relatively narrow portions of their inspection windows. Also included may be windows of intermediate widths for determining when tolerance limits are being approached, as well as lines for measuring the clearance around the code symbol.
