  • Page 22: Examining The Results

    Examining the Results Examining the Results This section details how the results of the verification can be viewed and analyzed. 1D & 2D Verification Main Tab The Main tab shows a snapshot of the verification results. Acceptance Criteria: Provides a Pass/Fail grade for the barcode and is dependent on the Application Standard selected.

  • Page 23: General Characteristics Tab

    Examining the Results as data parsing error or x-dimension range, the grade is shown as an F. For example, if a symbol receives an overall grade of A(4.0) but fails for a X-dimension out of range, grade trending marks the data point as an F. Enable or disable grade trending using the Trending checkbox in the Application Settings menu and set a tolerance range for the number of verifications (x) allowed to fail out of the total number of verifications (y) specified.

    Settings Settings This section describes the settings you can make and the options you have in the TruCheck Verification window. Accessing the Settings Menu To access Settings, select the Settings icon in the upper left hand corner of the interface. Application Settings The content of the Application Settings window depends on the Application Standard selected, since the application standard setting automatically selects many parameters.
  • Page 30 Settings Th GS1 application standard allows codes to be verified according to GS1 General Specifications. GS1 General Specifications contain several categories of applications which are described in its Tables 1-11. You can select from among these tables to specify the application category for your codes. Consider the following examples: Note: Since the X-dimension of the decoded symbol is used to deduce which table applies, it can be incorrect if your X-dimension is outside of the range allowed in your application.
  • Page 31 Settings UDI/HIBC The UDI/HIBC application standard checks symbols that meet UDI requirements using either GS1 or HIBCC guidelines. You must specify either ISO 15415 grading or ISO 29158 grading. Select Dot Peen if applicable. Since the data content required for UDI compliance varies depending on the medical device, only the data format (not the content) is validated.
  • Page 32 Settings Generic Apply the Generic standard option when you are grading a code that is not expected to adhere to any pre-defined industry conformance standard, and so it can be customized with specific settings for: Aperture Size Minimum Acceptable Pass Grade Minimum and Maximum X-dimension Grading Method: ISO 15415 or ISO 29158...
  • Page 33 Settings Data Parsing and Validation Auto Apply the Auto application standard option to allow the verifier to select the correct application standard based on the structure of the barcode data. If the data structures for GS1, HIBCC, or MIL-STD-130 standards are detected within the symbol during verification, the verification is executed using the correct application standard.

  • Page 34: Grading Standards

    Settings Grading Standards For any Application Standard selected, you must use either ISO 15415 or ISO 29158 (AIM-DPM) depending on your application. ISO 15415: Reports and displays according to ISO/IEC 15415 which is typically used for label based codes. ISO 29158 (AIM-DPM): Select to use the AIM-DPM verification standard. ISO 29158 (AIM-DPM) can used with or without the Dot Peen selection.
  • Page 35 Settings ISO 15434: The ISO 15434 option checks data for many industry standards which encode information using ISO/IEC 15434 data structures. These codes generally begin with the sequence )]><RS>nn<GS> where nn are two digits which are typically 05, 06 or 12. MIL-STD-130 and some shipping container applications use this formatting style.

  • Page 40 Grading Standards and their Parameters ANU (Axial Non-uniformity) is the amount of “out of square” the modules are, that is, a measure of the overall aspect ratio of the symbol. For rectangular symbols which are supposed to be non-square, the ANU parameter reports the deviation from its “correct”...
  • Page 41 Grading Standards and their Parameters TQZ (Top Quiet Zone) is a grade based on imperfections in the quiet zone, which is a one-module area above the Top Clock Track. ULQZ (Upper Left Quiet Zone) is the top quiet zone above the upper left quadrant. Used only for 2 and 4 quadrant symbols, this is the grade based on the segment of the quiet zone above the top clock track of the left quadrant.
  • Page 42 Grading Standards and their Parameters ULQRTR (Transition ratio for Upper Left Quadrant Right Clock Track): Only for 2 and 4 quadrant symbols, this is the grade based on the clock track segment to the right of the upper left quadrant. For a 2 quadrant symbol, this is labeled LQRTR URQRTR (Transition ratio for Upper Right Quadrant Right Clock Track): Only for 2 and 4 quadrant symbols, this is the grade based on the clock track segment to the right of the upper right quadrant.

  • Page 43: Iso 29158 (Aim-Dpm) 2006 Grading Parameters

    Grading Standards and their Parameters AG (Average Grade of Damage across many parts of the Finder Pattern) is a grade that considers the accumulated effect of damage to several parts of the finder pattern. Five values are averaged together. One of these is the lowest of all the grades associated with all the clock track segments, namely TCT, TTR, TQZ and RCT, RTR, RQZ.

  • Page 44: Traditional (Non-Graded) Parameters

    Grading Standards and their Parameters Fixed Pattern Damage grading parameters, except for AG, are not renamed, but are functionally different since the global threshold and modulation grading scale are different. As symbols obtain a significantly higher grade according to AIM- DPM than ISO 15415, grading according to AIM-DPM is appropriate only when called for in an application specification.

  • Page 45: Mrd

    Grading Standards and their Parameters The percentage of the light background accounted for by the difference between the bars and spaces. PCS was defined as a measure of contrast the human eye perceives long before and outside the context of measuring barcode contrast. The measurement is made relative to the brightness of the background.
  • Page 46 Grading Standards and their Parameters 3. SC: Symbol Contrast Measures the contrast between the brightest space and darkest bar. The result is assigned a letter grade of A, B, C, D, or F, with A being the highest contrast. The contrast is the difference between the maximum reflectivity (lightest or best space) and the minimum reflectivity (darkest or best bar).
  • Page 47 Grading Standards and their Parameters 6. Def: Defects The worst-case change in reflectance within a single bar or space is a defect. The largest difference in reflectivity found in a single bar or space is measured as a percentage of the symbol contrast and assigned a letter grade. Defects measure breakups or voids within bars, ink spots in spaces, or even the grain of a substrate in spaces.
