Metric
The Metric option allows you to choose between measurements being reported in inches or metric units
(mm/microns).
Quiet zone processing
The Quite Zone for a linear (1D) code is a clear space preceding the start character of a barcode symbol
and a clear space following the stop character. The quite zone for a two-dimensional (2D) code is a clear
region (free of markings or text) surrounding the 2D symbol’s finder patterns (finder patterns allow the
symbol’s location and orientation to be determined). Quiet zones are part of the barcode and the appropriate
quiet zone space is required to verify a barcode.
The QRCode > 1X option toggles the quiet zone processing between 1X (where X is the nominal cell width)
and greater than 1X depending on the QR symbol being graded. The QRCode > 1X option is disabled
(unchecked) by default indicating the quiet zone for a QR code is one cell width around the perimeter of the
finder patterns.
When checked, the LVS-95XX software uses 2X (two cell widths around the perimeter of the finder patterns)
as the quite zone for Micro Code QR symbols and 4X (four cell width) as the quite zone for QR code
symbols. ISO/IEC rules state 2X and 4X are the quiet zone requirements for Micro QR Code and QR Code
respectively. Checking the QRCode > 1X option ensures ISO/IEC quiet zone compliance for QR Code and
Micro QR code.
