| User's guide |
This is a
simple to understand, jargon free, tips rich guide for all new
users of an Sandilyam PC Verifier.
Applies to the following verifiers:
PC6000 (x05,x10, x15), PC6500 (x05,x10, x15), PC7000 (x05,x10,
x15)
SOFTWARE INSTALLATION
Insert the CD Rom in the disk drive.
The installation will run automatically. We recommend that you
install the program as prompted by default under C:\Program
Files\Sandilyam\Verifier.
When prompted for passwords: Enter the password for each read
head as written at the back of the manual cover page. Please
note that if you have purchased the basic version (eg: PC6000
as opposed to PC6015) then there is no password to enter. Depending
on the version purchased
you will have up to three passwords to enter. Enter the read
head serial number and the passwords for this serial number.
Repeat for each readhead.
SOFTWARE UPDATES
The software is updated on a regular
basis. You will find the latest version for free download on
the website on http://www.barcodeglobal.com/download.html
To find out if you have the latest version already installed,
open the program on your PC and click on the
icon. Check the software version number (example 2.0.14.1) on
your software against the version for download on the website.
The Software would be provided upon request through e-mail.
READER INSTALLATION
Please always handle the read head with
care to avoid damaging its optics and losing its accuracy.
You plug the verifier to the serial or the USB port of your
computer, depending on your verifier connection. For USB connected
verifiers, you will have to install the USB drivers for each
verifier that you connect to the PC. The drivers are loaded
on the installation CD or can be downloaded from our webpage
download page. If you have the installation CD, we recommend
that you insert it in the PC prior to first connecting the verifier.
Then you will be guided through the installation of the driver.
Once the reader has been connected to the PC and the drivers
installed (for USB verifiers only), open the Sandilyam PC Verifier
program. the software will identify the read head and display
its serial number. Verification can start.
READER NOT FOUND
If the message "reader not found"
appears check that the reader is properly connected and powered,
that the red L.E.D.s are on and try again. If it still fails,
contact your Sandilyam reseller. |
TWO READ HEADS CONNECTED TO
THE SERIAL PORT THROUGH A SWITCH
Please note that the switch has to be
supplied by Sandilyam.
In case your equipment is configured as such, we recommend that
once you have installed the equipment you proceed as follows:
Say you want to use reader A. Turn the switch on A, then open
the program. Reader A will be powered and you are ready to verify.
You can check that the serial number of reader A is displayed
in the command window of the verifier. If you then need to use
reader B, close the program down. This will stop powering reader
A. Then turn the switch box to B and then open the program again
to start verification with B. When you have finished, close
the program. Both units should be out of power.
If the L.E.D.s of a reader are still on, make sure the switch
box points to this reader, then open the program and close it.
This should switch the reader off. If not then you are running
an old version of the verifier and we recommend that you download
the latest version.
CALIBRATION
You must calibrate the reader when you
first use it. To calibrate the reader you must use the calibration
card supplied by Sandilyam. It is kept inside the manual. Please
keep it away from the light to protect its photographic properties
and maintain it in pristine conditions. If at any stage the
calibration card is damaged or if you think its properties might
have altered, please order a fresh one from your Sandilyam reseller.

To calibrate:
1. Open the program and click on Calibrate in the Options
menu of the command window. The calibration dialog box will
be displayed.
2. Enter the Minimum and Maximum values as written at
the back of the calibration sheet. By default the values are
set at 3 and 92 (or 90 for later versions)
but the values of your calibration cards could be different
and should be set accordingly.
3. Place the reader neatly over the calibration barcode
(use the big one for the PC7000, the medium one for the PC6500,
the small one for the PC 6000)
4. Read the code ten times. You do not need to move the
reader when you do 10 scans for a calibration.
5. Click OK.
If you move your reader from one PC to another, you have to
calibrate the reader for each PC it is used with.
HOW OFTEN DO YOU NEED TO CALIBRATE
There is no recommended frequency for the calibration as it
is dependant on how often the verifier is used and how it is
stored. The reader properties will be altered by significant
changes in temperature or humidity or pressure or if the ambient
light at calibration is very different to the one at the verification
stage. (see chapter about ambient light).
To monitor you verifier and set up an adequate frequency for
calibration, we recommend that after calibration, you make a
10 scan verification of the calibration code and save the results.
Then at a later stage, you scan again the same calibration code
and check the results against the original ones. If there are
significant differences in the percentage values of for example
the decodability parameter, then the time has come to re calibrate
the read head.
Please note that the calibration option in the Setup screen
of the software allows you to setup a warning message when calibration
is required at the specified date. |
USING
THE UNIT
PC7000
Place the verifier neatly over the surface
of the barcode as per the illustration. make sure the scan line
is straight across the code. The scan line is about 7mm from
the front of the unit.
Always close the hinged flap at the front of the unit.

ABOUT THE AMBIENT LIGHT
When we verify a printed barcode, we look at its physical properties,
independently from the environment particularly the ambient
light. Ambient light at the scanning stage at the retailers
cannot be anticipated and should not influence the results at
the verification stage.
The Sandilyam verifiers have been built to avoid the influence
of the ambient light as much as possible. If properly used,
our verifiers cover most of the barcode, thus creating an enclosed
area around the barcode.
However, there is still some minimal access for the ambient
light. Also with some packaging, it is impossible to cover properly
the scanning area and finally some shiny or even worse non opaque
materials leave us with little chance to protect the scanning
from the ambient light. So we recommend that you avoid scanning
too closely or directly under a source of light. particularly
when scanning under sunlight, fluorescent light, high pressure
sodium or mercury vapour lamps.
HOW MANY SCANS SHOULD YOU AVERAGE ON
?
It is recommended to scan the barcode at different heights and
average the results in order to give a more accurate overall
grading. You can average up to 10 scans of the same barcode.
The ISO 15416 standard does not specify how many scans should
be averaged over but gives a methodology based on results achieved
on previous print runs of the same symbol. The amount to average
over goes from 2 scans to 10 scans as the code goes from a consistently
good barcode to a consistently defective barcode.
Averaging is about consistency of the grading throughout the
height of the barcode. Take 3 scans of the barcode: one at the
top, one in the middle and one at the bottom. If the results
are good (A or B) and very consistent (same grade each scan)
then a 3 scans average is enough, if the result are not so good
(C, D or F) and not so consistent (1 grade difference) then
go for a 5 scan average, if the results are not consistent (results
with 2 grade difference or more) then go for a 10 scan average.
IF A BARCODE DOES NOT READ ON YOUR VERIFIER
?
There are several possibilities. First, make sure that the verifier
is being properly used and try again at another height of the
barcode, to make sure that the scanning line "catches"
the barcode. If it still fails to decode, then it means that
the barcode is defective. Please note that even if there is
no read, you can display the reflectance profile by clicking
the relevant box at the top of the reflectance profile screen.
This will give you the reflectance values of the symbol and
some good indications as to where the problem might have occured.
CASE STUDY. Barcodes printed on film often present problems.
The usual problems occur when:
- The material is non opaque. The scanning light goes through
and does not reflect properly back into the unit. In that
case, scan the symbol on top of a black background and scan
it also on top of a white background and keep the worst
result. Alternatively, in the case of a packaging that has
not been filled, if you know the colour of the product (eg:creams,
lotions,..) use this colour for the background.
- The material is shiny. The reflexion is distorted and
gives an inaccurate perception of the dimensions.
- The barcode is printed on a film layer stuck on top of
an opaque packaging: If the barcode is printed under the
film, the scanning light
has to go through a thickness of film before it reaches
the barcode and there is a double effect of refraction and
reflection of the light.
The barcode is printed on top of the film, but the light
that goes through is then caught by the bars when it goes
back through the
symbol after being reflected.
The consequence is that a verifier (hence any scanner) will
have an exaggerated perception of the dimension of the bars
that will
give a poor decodability grading
SAVING THE DATA
Sandilyam PC Verifier is dedicated to giving you all the tools
to save, analyse and circulate the verification data. When you
scan a barcode for verification, the results can be saved on
your PC or on a disc as a .SCN file, that can then be opened
on any PC where the Sandilyam PC verifier is loaded. When you open
the file, all the data is displayed and can be printed off,
as if you had just proceeded to verifying the barcode. This
enable you to have remote diagnostic immediately (the file can
be sent by email). This also allows you to store verification
data for further use. The software can be set up to save all
the scans automatically or this can be done manually. The manual
saving allows you to retain only the important verifications
and to give a relevant file name.
An optional program San File Data Extractor has been developed
to be used in conjunction with Sandilyam PC Verifier. This program
allows you to select verification files in a table and is an
useful tool for statistical analysis. Contact your Sandilyam Reseller
for more information.
