Determining the reading distance

The typical reading distances are shown in figure 4.5.
In general, the read field increases with the reading distance. This also results in a decrease
in the resolution, however.
For reading distances between 100mm and 130mm, particularly homogeneous illumina-
tion of the image field is ensured by the integrated illumination.

Notice!
Please notice that the real reading distances are also influenced by factors such as labeling
material, printing quality, scanning angle, printing contrast etc., and may thus deviate from
the reading distances specified here.
Depending on code type, code size, cell or modulus size and position of the code in the
field of view, reading can also occur while in motion.

Cleaning

 Clean the housing window of the LSIS 22x with a soft cloth after mounting. Remove all
packaging remains, e.g. carton fibers or Styrofoam balls. In doing so, avoid leaving
fingerprints on the front cover of the LSIS 22x.
Attention!
Do not use aggressive cleaning agents such as thinner or acetone for cleaning the device.
Use of improper cleaning agents can damage the housing window and display.
