Step 3 Consider Read Range and Scan Width
a) Verify that the labels to be scanned will pass through the readable range. Opti-
mum decode rates can be expected at the center of the depth of field (halfway
between minimum and maximum read range) for a given bar code density.
b) Note the approximate scan width at the specific distance the labels will be pass-
ing through.
Read range is the distance from the scanner in which a passing label can be read.
For the MS-810, read range varies from 2 to 30 inches depending on label density
and optical version of scanner.
Scan width is that distance across the scan arc in which a label can be read. For a
moving label, the closer to the scanner, the shorter the time it will be within the
scan width, and hence the fewer scans it will receive.
