Scaling adjustment 

As a third step, scale adjustment is performed.

The process involves using the live image display to position the Data Matrix code, 
designated as Dnom = 0.5, as precisely as possible in the middle of the cross hairs 
and perpendicular to the image section. The software has a setting for the Dnom 
value in millimetres (mm). The value of 0.500 is the required setting in mm. The 
scaling adjustment sets the pixel size automatically so that the known correct size of 
the calibration symbol is shown precisely in the measurement result. Following scale 
adjustment, the code is measured automatically twice. The first measurement uses 
red light and the second white light. The results should be documented and are used 
as a reference for the next calibration (i.e. as part of test equipment monitoring).  
The symbol with Dnom = 0.75 mm is used for the camera module with a 16 mm focal 
length.
