The REA PC-Scan LD4 is a bar code verifier made in Germany
which was developed in conformity with international
standards. It is especially designed for measuring barcodes
with highest precision.
The REA PC-Scan LD4 is a guarantee for highest measurement
accuracy. It provides the following unique features:
■ fully automatic contrast calibration before every scan
■ integrated metric standard for precise width and length
measurements
■ constant lighting angle of 45° over the entire scan width
of 155 mm or 240 mm
■ laser illumination with a wave length of 670 nm
■ constant sensor angle of 90° over the entire scan width
■ constant measurement distance over the entire scan width
■ contact-free measurement
■ aperture 10 to 20 mil in combination with up to 240 mm
measure width (exemplary configuration)
■ hollow body measurement adaptor for barcodes on hollow
bodies available
■ two device variants available: 155 mm scan width and
240 mm scan width
The combination of state-of-the-art technology, process
reliability and intuitive operation makes the REA PC-Scan LD4
globally unique in its class.
Final statements „Pass“ or „Fail“ are central display elements
and enable an immediate result. The simultaneously displayed
details allow for an immediate and exact barcode quality
analysis.
Thanks to the graphical display of the measurement results
different measurement aspects can be recognized and
assessed quickly and reliably. The display is optimized for easy
understanding of the meaning of the measurement results.
If required, evaluation reports are automatically saved and
supplemented with a job number in the file name.
REA TransWin 32 evaluation software
The operation can be protected by user administration or password. For individual complete settings, a profile can be created. This can be called up later by the push of a button for routine verifications. The correct measurement setting can thus be created quickly and safely in just one step.
For subsequent data exchange, verification reports can be generated as a PDF file and exported as a text table (CSV).
Comment features enable individual user comments within the report.
With the REA PC-Scan LD4, you can find out precisely why the read rates are low. The detailed evaluation results allow a lasting optimization of the code quality.
Optional software extensions
REA Article Look Up Software
An additional verification is carried out using database data.
Each item number is checked against individual data since there is a separate entry in the database for each product.
In a simple case, it is checked, whether a read item number exists within the code. In the extended case, e.g. data and prices can be checked.
REA ScanLink
REA ScanLink is an optionally available software solution for extended standard-compliant code verification. Data structures are regulations about how information must be stored in a code. Ideally, this regulation is equal for all, so that all code users know the meaning of the code contents. The generally valid regulations for data structures are specified by ISO standards ISO / IEC 15459-x).
REA Code Analysis
The REA Code Analysis is an optional software extension for all REA verification devices. In many applications, data is used which is built according to an internally defined structure (proprietary data). REA Code Analysis provides these requirements in a table. The code content is thus checked for its correctness.
Optional Symbologies
A variety of different codes can be measured as standard with
the REA PC-Scan LD4: EAN-13, UPC-A, UPC-E with/without
ADD-ON, EAN-8, 2/5 Interleaved with/without check digit,
ITF-14, Code 39 with/without check digit, PZN-Code, Code 32,
Code 128, GS1-128 with/without content verification,
GS1-Databar (limited, expanded, stacked).
The „Optional Symbologies“ software expansion makes less
common bar code types available: 2/5 3 Bars, 2/5 5 Bars, 2/5
IATA, 2/5 Baggage, 2/5 DHL Express (Freight code), Code39
Full ASCII, Code93, MSI, Plessey, Code 128 UPU, Code 39 UPU,
Code 39 HIBC, Code 128 HIBC, Codabar Monarch (18), LAETUS
Pharmacode, LAETUS Mini Pharma Code.
The included measurement program measures reflectance
profiles of unknown codes or any other structures. A metric
and a contrast assessment can then be made.

■ measurement according to ISO/IEC 15416 or ANSI X3.182
■ optional parameters in accordance with the respective bar
code standards for optimal print process control

be cloned for multiple devices
■ adjustment of desired minimum quality with automatic
target/actual comparison
■ auto discrimination of the most important bar code
symbologies
■ automatic code size and check digits monitoring
■ multiple measurement with averaging from up to 10 single
measurements
■ verification and visualization of quiet zones with an
extended area
■ ratio monitoring for two bar width codes
(e.g. Code 39, 2/5i)
