How to scan?
Here are some notes on how to get the best scan performance (see Fig.)
The scanner must be kept at a slight angle to the bar code. (Hold the scanner perpendicular to the barcode.)
Cross the red line should be addressed as an aiming aid centered on the code. So that the camera is aligned
with the center of the code. (The scanner cannot recognize the label correctly if it is not completely covered by
the camera and recorded).
Cross the red line is smaller and narrower when the scanner is closer to the code. Smaller codes should be
read with a smaller reading distance, with larger codes, the distance chosen such that the camera can be fully
grasp it.
Testing the Scanner
The adjacent bar code (code 39) is for testing the scanner,
The module size is 0.5 mm (20 mil)
