Performance; Reading Diagrams - Datalogic DS6100 Installation Manual

DS6100
The formulas to calculate α maximum depend on various parameters such as:
label height, number of scans per second, code motion speed, etc. To obtain α
maximum for your application, please contact your Datalogic representative.
You must remember that the decoder will be able to
read the label with a tilt angle between + α max and - α
max as shown in Figure 3.4 (the shaded zones are the
NO READ zones).

3.2 PERFORMANCE

It is possible to change the focus of the DS6100 in order to reach the reading
distance expected. The scan rate is 800 scans / sec.
Refer to the diagrams in par. 3.3 for further details on the reading features.
These diagrams are taken on various resolution sample codes at a 25 °C
ambient temperature depending on the conditions listed in Figure 3.5.
If standard models do not satisfy specific requirements, contact your nearest
Datalogic distributor, supplying code samples, to obtain complete information
on the reading possibilities.

3.3 READING DIAGRAMS

The diagrams on the following pages show the reading distance for barcodes
with different densities and refer to two laser beam apertures.
The following table illustrates the convention used for reading diagrams and
the operating conditions of the scanners that refer to these measures:
