Basic Operations
Illumination Sequence
The POWERSCAN D8590 is configured to provide the broadest reading capabilities “out
of the box”. Just point and shoot to read most marks. This is achieved by combining the
illumination system with advanced decode algorithms. The POWERSCAN D8590 automatically
cycles through a default combination of the illumination zones each time the user pulls the
trigger to decode a mark. The imager will then lock onto the settings used in the last good
read and move those to the first step in the next sequence.
The POWERSCAN D8590 has four steps defined in this default illumination sequence:
1. Low Angle Illumination with Low Resolution Image
Low Angle
Illumination
2. Low Angle Illumination with Full Resolution Image
Low Angle
Illumination
3. Blue Dome Illumination
Blue Dome
Illumination
4. Red Dome Illumination
Red Dome
Illumination
With ESP Software, the user can change this sequence or define a different sequence. It
is possible to have one step to as many as eight steps defined. ESP allows the user to
evaluate the best settings.
Note: Decode speed can be improved with fewer illumination steps.
Note: Hovering over an uploaded image in ESP with your cursor will display the settings
used to capture the image.
In addition to the general purpose sequence, a special sequence has been defined for dot
peen marks. This adds additional X-Mode pre-processing to the sequence steps, allowing
you to read some of the most challenging direct part marks with ease.
