Digital Bar Code

Click the Digital Bar Code tab and the Start button to view a digitized representation of the symbol in front of the scanner.

This routine is useful for conveying a sense of the symbol's readability and graphically indicating bad or unreadable portions of symbols or extraneous "noise". A green waveform indicates a decoded symbol; a red waveform indicates an undecoded symbol or other object.

The red triangles represent the width of the scan beam relative to the symbol. The upward pointing arrows indicate the symbol's quiet zone.
