Positioning the model on the object holder

 

 
 

Positioning: 

The correct positioning of the model on the object holder is indispensible for correct measuring 

results. The positioning must be maintained in respect to the "height alignment". 

 
 
 

Height  alignment: 

The scanner has a definite height measuring range. If the object to be measured is located outside 

this range, no measuring values will be measured there. This means that the finished scan will 

exhibit holes or have a cut-off effect. 

The scanner has a height measuring range of +/-25 mm, i.e. 50 mm in total. 

 

 
 
 
 
 
 

Incorrect height alignment is one of the most frequent reasons for unsatisfactory 

scanning results!
