6.1.3 Determining the reading distance
In general, the read field of the code reader becomes larger with increasing reading distance. This also
results in a decrease in the resolution, however.
The following figures show typical reading distances for the individual optics models of the code reader.
For the relationship between camera distance and read field see figure 6.6.

Code reading while in motion is dependent on the code type, code size, cell or modulus size of
the code and the position of the code in the read field of the code reader.
Please note that the actual reading distances are also influenced by factors such as labeling
material, printing quality, reading angle, printing contrast etc., and may thus deviate from the
reading distances specified here.
