MiniScan MS-320X Integration Guide
Usable Scan Length
The decode zone is a function of various symbol characteristics including density, print
contrast, wide-to-narrow ratio, and edge acuity. Width of decode zone at any given distance
must be considered when designing a system.
Calculating The Usable Scan Length Method on page 2-10 provides a detailed description
of how to calculate the usable scan length. The scan angle is provided in Table 4-2 on page
4-4.

Notes:
1. CONTRAST measured as Mean Reflective Difference (MRD) at 650 nm.
2. Near ranges on largely depend on the width of the bar code and the scan angle.
3. Working range specifications: Photographic quality symbols, pitch = 15º, skew = 0º,
roll = 0º, ambient light < 150 ft. candles, and temperature = 23 °C, Vcc = 5V.
4. Measured from the front of the scanner.
