Calibration
Calibration informs the verifier about the grey scale levels and pixel dimensions of the reader. This way, the verifier can
report Symbol Contrast and X-dimension in true physical units.
For ISO compliant barcode verification, make sure that the verifier is in a calibrated state.
For Standards Based Grading, the verifier will not report all quality parameters without calibration.
In an uncalibrated state the verifier does not report:
lAperture and Symbol Contrast (SC) for ISO/IEC 15415/15416 applications
lMinimum Reflectance (MR) for ISO/IEC TR29158 (AIM-DPM) applications
When the verifier is used in an uncalibrated state, neither the aperture nor Symbol Contrast (SC) for ISO/IEC
15415/15416 applications and Minimum Reflectance (MR) for ISO/IEC TR29158 (AIM-DPM) applications is reported.
Note: In an uncalibrated state, the verifier does not report aperture value, but uses the default aperture selection:
Auto 80%.
To calibrate the DataMan 475:
1. Click the Calibration icon in the top left corner in the TruCheck Verification window.
2. Enter the Rmax and Rmin values from the calibration card.
3. Click Center Target.

4. A live image appears in the Calibration screen. Center the verifier over the Master Symbol on the Data Matrix
symbol of your traceable calibration card.
5. Click Start Calibration.
14
Setting Up Your DataMan 475 Verifier

6. The verifier goes through a series of lighting calibrations. After a successful calibration, the Calibration Complete
window pops up:
Tip: Click Discard Calibration to remove all calibration values and return the verifier to an uncalibrated
state.
Calibrate your verifier as needed to ensure accurate verification results:
lMonthly calibration recommended:for laboratory or QA environment, which is free of dust, vibration, bright
sunlight or oil particulates
lWeekly calibration is recommended: for production environments, where contaminants exist
lCustom frequency calibration recommended: where internal quality guidelines demand more frequent
calibration
Note: Store the calibration card away from direct light where contaminants do not compromise the
calibration symbol.
Tip: Enable a calibration reminder to alert you about the next scheduled calibration. After enabling the
calibration reminder, set the number of days for prompting a calibration reminder.

Verifying a 2D Barcode
To verify a Data Matrix code or a QR code in the TruCheck Verification Window:
1. Navigate to the Main tab.
2. Click Go Live and center your symbol in the field of view, or press and release the trigger button to Go Live.
Note: After selecting Go Live, the button changes to Verify.
3. Draw a selection region around the code to be verified, if necessary.
Note: The region must be drawn around the outside perimeter of the code including quiet zones. More
information on properly defining regions is explained in Selecting Regions on page18.

UsingYour DataMan 475 Verifier

4. Click Verify, or press and release the trigger button on the verifier to begin verification.
Note: The following screenshot shows a successful 2D barcode verification. Additional details in the
TruCheck window are displayed depending on grading and application standards.
Note: Use the tool bar buttons and tabs on the screen for in-depth analysis of codes. For more information, see
Examining the Results on page21.
Selecting Regions
Requirements for specifying regions on the image are the following:
lThe code is off-center.
lTo speed up the verification process on verifiers with large fields of view. Defining a small sampling area
increases the speed.
lTo restrict a region for image brightness adjustments when grading according to AIM-DPM (ISO/IEC 29158).
lTo specify a barcode for verification when more than one barcode is present in the field of view.
If you do not define a region, the whole image is used for verification.
To define a region:
1. Position your cursor where you want the region to start, click and drag.
2. Release the button when you are done.
For Data Matrix symbols and QR Codes, draw the region around the outside perimeter including quiet zones of the code
to capture the entire finder pattern within the selection to properly grade the code.
When verifying a 1D symbol, select a region that includes the full width of the barcode including both quiet zones:

Standards Based Grading
Standards based grading is an option in the DM475V that uses true verification algorithms to produce well-defined,
consistent results from the image of a code captured by a barcode reader in a real-world setup. In practice, the setup
needs to be as close as possible to a fully ISO compliant verifier – lighting angle in particular. The measurements are
calculated the same way as with a verifier, so the closer the setup is to a true verifier, the closer the results are to true
verification. With the same lighting setup, the measurements between standards based grading and verification
converge. This method is called standards based grading because as the quality of a code changes during a production
run, grades change in about the same way as with a verifier. Standards based grading is the closest way to achieve
verification results without having to conform to specific lighting angles, distances, or every ISO standard parameter.
For Standards Based Grading, the verifier can be used without calibration but not all quality parameters are reported.
When the verifier is used in an uncalibrated state, neither the aperture nor Symbol Contrast (SC) for ISO/IEC
15415/15416 applications and Minimum Reflectance (MR) for ISO/IEC TR29158 (AIM-DPM) applications is reported.
Note: In an uncalibrated state, the verifier does not report aperture value, but uses the default aperture selection:
Auto 80%.
Verifications of Multiple Symbols
To enable multiple barcode verification feature, complete the steps below in DataMan Setup Tool before initiating
verification in the TruCheck window.
1. Open DataMan Setup Tool.
2. To connect to the DM475 Verifier double click on the icon in the automatically generated list on the Start up
