The purpose of calibration is to optimize the scanner's optical settings (focus, gain, and
tracking) and scan speed to obtain the highest read rates in one or several symbol positions
as required by the user's application. This section includes the overall steps in calibration
and specific steps for calibration by ESP, serial command, and embedded menus. For
most applications calibration is the only optical setup required.
Changes to motor speed, focus, speed, gain, tracking, and AGC can also be made individually
by manual command.
Calibration Methods
There are three ways to initiate calibration:
• ESP Calibration menu
• Serial command
• Embedded menu
Note: Calibration does not function with PDF417 symbols. However, you can substitute a
Code 128 symbol with the same mil size as your PDF417. When you do this, enable Code
128 and disable Raster scanning. After calibration, switch back to PDF417 and Raster
scanning.
