Note
Creating optimal reading conditions
When you install the optical reader, make sure that the code to be read is visible to the optical
reader with the best possible
quality. You can optimally set up and align the reader using the
WBM ("Application > Program > Image acquisition").
When installing the reader, pay attention to the following points:
• The viewing angle to the code may vary between 40° to 90° and 80° to 90° depending on
the code type.
You can find more information on the viewing angle in the section "Performance
characteristics when reading codes (Page 38)". You can find information on optimal setup
and alignment of the reader in the section "Connecting and setting up the reader
(Page 132)".
• Note that the mounting location and viewing angle may affect the readability of the code.
– There must be as few reflections as possible in the code field.
– The code field must be uniformly lit without shadows.
• Keep enough distance between the individual codes.
• The distance between a two-dimensional code and image border must be at least 2 cell
widths (dot width or line width).
Infrared radiation via built-in infrared ring light
Infrared radiation occurs when using the built-in ring light "6GF3540-8DA4x". Use
appropriate shielding or eye protection. Do not look into the lamp for a long period during
