3.3 Position the ReaderThe ABR is able to decode code labels at a variety of angles; however significant angular distortion may degrade readingperformance.When mounting the ABR, consider these ideal label position angles: Pitch or Skew 10° to 20° and Tilt 0°. The reader canread a code at any tilt angle provided the code fits into the Field Of View (FOV).Note: Because the ABR is omni-directional on the code plane, the Pitch and Skew angles have the samesignificance with respect to the code plane. However in some advanced code reading applicationsperformance can be improved by modifying the Skew angle.The Pitch, Skew and Tilt angles are represented in the following figure.No Pitch, Tiltor SkewPitchminimizeSkewassure at least 10ºTiltany angleinside FOVFigure 8. Code Reading Orientation—Pitch, Tilt, and Skew AnglesUse the follow the suggestions for the best orientation:• Position the reader to avoid the direct reflection of the light emitted by the ABR reader. It is best to use at least 10°for the Skew angle• Use a Pitch or Skew angle of 0° in some cases, such as low contrast or low illumination• Align the reader to fit linear barcodes into the horizontal FOV for best performance (because linear barcodes arerectangular). The ABR can read labels with any tilt angle.FOVVFOVHFigure 9. Code in FOVNOFigure 10.
