Title: Consider read range and scan width

Description: Details on how to consider read range and scan width with MS-911 high speed reader.

Issue: How do I consider read range and scan width with the MS-911?

Solution: 1. Verify that the bar code to be scanned will pass through the readable range. Optimum decode rates can be expected at the center of the depth of field (half-way between minimum and maximum range) for a given bar code density.
2. Note the approximate scan width at the specific distance the bar code will be passing through.

Read range is the distance from the scanner in which a passing bar code can be read. For the MS-911, read range varies from 1-9 inches (standard model) depending on bar code density and optical version of scanner.

Scan width is that distance across the scan arc in which a bar code can be read. For a moving bar code, the closer to the scanner, the shorter the time it will be within the scan width, and hence the fewer scans it will receive.
