Calibration Options
Shutter Speed
Definition: Unless an application is a static setup, the shutter speed setting should be
configured by the user based on the application. For dynamic applications, the
user should configure the shutter speed setting so the calibration process can
optimize the gain for that setting.

Default: Disabled
Options: 0 = Disabled
2 = Fast Shutter
Note: The following table shows general guidelines for shutter speed configurations based on
various line speeds. The configurations shown depend on the Imager's optical configuration,
and on symbol element size.
Shutter Speed
0 - 250
250 - 750
750 - 1500
1500 - 2000
2000 - 2500
Shutter Speed Disabled
When this feature is disabled, the shutter speed is fixed and is not part of the calibration
process.
Shutter Speed Enabled
When this feature is enabled, shutter speed will be calibrated to provide the best possible
image quality and performance.
Fast Shutter
The calibration process will concentrate on achieving the fastest possible shutter setting that
will still provide good performance. The image quality or contrast may not be as good as
what would be achieved with the Enabled setting. The calibration process is not designed to
choose the fastest shutter speed that can decode a symbol, but rather to optimize for the
fastest shutter speed that still provides good image quality.
