3.3 PERFORMANCE
The LazerData 12000 Scanner is available in four standard models varied by
optical resolution characteristics (see section 1.3).
The standard resolution model is a general-purpose model whose optical
resolution allows code reading from 0.20- to 1.00-mm (8- to 39-mil) narrow bars in
the zone between 50 and 400 mm (2.0 to 15.8 inches) from the emission window.
This model can distinguish between high density codes (between 0.20 mm and 0.30
mm, or between 8 and 12 mil) and low density codes (above 0.33 mm or 13 mil) by
programming the software resolution parameter (see the section "Scanner
Resolution" in the LDHOST Help Online).
The very high resolution model has an optical resolution that allows reading very
high density codes (typical values from 0.10- to 0.20-mm, or from 4- to 8-mil,
narrow bars) in the zone from 55 to 125 mm (2.2 to 4.9 inches) from the emission
window. The software resolution parameter for this model should be set to high (see
the section "Scanner Resolution" in the LDHOST Help Online).
The Raster model R1 is a raster model used to read codes from 0.20- to 1.00-mm
(8- to 39-mil) narrow bars with a raster aperture of about 12 mm (0.47 inch) at a
200-mm (7.9-inch) distance.
The Raster model R2 is a raster model used to read codes from 0.20- to 1.00-mm
(8- to 39-mil) narrow bars with a raster aperture of about 40 mm (1.6 inches) at a
200-mm (7.9-inch) distance.
Refer to the diagrams given in paragraph 3.4 for further details on the reading
features. These diagrams refer to the two standard optical models and are taken on
various resolution sample codes at a 25ºC (77ºF) ambient temperature, depending
on the conditions given in the notes under each diagram.
If standard models do not satisfy your specific requirements, send a representative
code sample of your labels to the nearest PSC Automation, Inc. distributor, who
will in turn supply you with complete information on reading possibilities.
