1 Introduction to REA ScanCheck 3n
REA ScanCheck 3n is a mobile bar code verifier for the contactless checking of the quality of
printed linear and stacked bar codes. It can be used for mobile quick checks on location. The
results of the check -
“Pass” or “Fail” - are indicated by an acoustic signal and visually with different
coloured LED displays. The detailed measurement results can be stored in the internal data
memory and shown on the colour display. It is also possible to print out the measurements with an
optionally available report printer. With the Option TransWin32, the ScanCheck3n can also be
connected with a PC with the REA TransWin32 software for remote control and evaluation via
network cable.
The important details from the measurement can be read off on the colour display.
Using the arrow keys it is also possible to scroll back and forth between further menu fields and
screens.
The further details can be made available by printing out the reports. With this, the device is
particularly well suited for use in print process checks and with the quality controlling of codes on
incoming goods.
When checking film masters, the applicability is limited to reading and decoding codes and the
comparison of their contents with a template.
Unlike in the case of reading a code by means of a scanner, consistent, reproducible measuring
conditions are always required for the verification of a code. This applies to both, the light source,
the lighting angle, lighting directions, the measuring aperture as well as the distance between the
device and test specimen. If the conditions change, variable, non-comparable measurement results
are the outcome.
A measurement result can provide information on quality deficiencies. In actual practice and
depending on the code application and the extent of the quality deficiencies, such deficiencies
range from barely noticeable up to a total failure of readability. What the response to quality
deficiencies should be depends very much on the respective application conditions and the scanner
used.
Scanners are usually not suitable for quality checks. Their task is to capture the codes as efficiently
as possible. When you attempt to carry out a quality check with a scanner, you only get information
on the ability of the scanner to read the codes. Different types of scanners show differences in the
reading characteristics.
When it comes to a quality check for printed/inscribed codes, however, the characteristic of the
codes is of interest, not the ability of a scanner to compensate for any deficiencies in the code
depiction.
Measuring equipment is subject to regular adjustment and test equipment monitoring (calibration).
This adjustment and test equipment monitoring can be performed by the user. Please observe
chapter 4 Adjustment and calibration in this regard. If the instructions on test equipment monitoring
are not complied with, changed measuring behaviour due to age, environmental influences or wear
remains unnoticed.
REA bar code verifiers analyse the print quality of bar codes in accordance with the international
standard ISO/IEC 15416. The analysis can be supplemented with optional parameters in order to
get more details; or it can be adapted to the respective requirement.
The previous traditional analysis has been replaced by the optional parameters.
