High

When Symbol Reconstruction Redundancy is set to High, the scanner will attempt to reconstruct symbols across multiple scan lines. A very large amount of redundancy checking will be applied to qualify the reconstruction result. This will require the effort level to rise to achieve a decode. This level of redundancy checking is helpful in avoiding misreads. Occasionally the symbol's level of data integrity may lead to a misread, but this setting requires enough matching data to protect the majority of data.

Note: Applications with a large amount of area coverage can use this setting. However, as aspect ratio decreases and line speed increases, High may not provide enough decodes to be useful. The Effort level may also require more time in some cases.
