Calibration Options - Microscan Quadrus MINI Imager User Manual

Calibration Options

This command specifies the operation of the imager's calibration feature. The default
configuration is set up to perform calibration on gain, focus, and symbol type. The
default shutter speed setting is disabled, because not all applications require shutter
speed, and when it is required, the application-specific settings tend to vary widely.
Note: Background Color
calibration setup. After successful completion of the calibration routine, the background
color will be set to the appropriate value, depending on the symbol in the field of view. The
Mirrored Image parameter (page 10-27) is not part of the calibration process, and it must
be configured appropriately prior to calibration.
Gain
Definition:
When enabled, gain will be calibrated to provide the best available image
quality and performance.
When disabled, gain is fixed and is not part of the calibration process.
Serial Cmd: <K529,gain,shutter speed,focus position,symbol type,WOI framing,WOI

Default:
Enabled
Options:
0 = Disabled
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.

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.

750 - 1500
1500 - 2000
