Checklist for measuring

The following points must always be observed for performing correct measurements:

1. The distance between the code and the device should vary only slightly. The

depth of field is contingent on the small distance between the lens and the

inspected area, limited to +/- 1 mm or 39,37 mils..

2. The code should always be positioned centrally in the middle of the field of

view.

3. The code should be aligned, as much as possible, in parallel or at an angle of

90° to the field of view in order to minimize any imprecisions due to staircase

effects at the code edges.

4. The automatic determination of the position defines the measuring area for 2D

codes and barcodes. The measuring area in the case of 2D codes is shown by

a superimposed green square and in the case of barcodes, by red

measurement lines. The square must surround the code in parallel to the code

sides.

The measurement lines must cross the bars of the code at an angle of 90°.

If this is not the case, the measuring area must be determined manually. (See

section 11.2)
