This height must be evaluated. 

All that is necessary is to reset

arrow while measuring.

Example: Use Zero Reset to Evaluate the Height of a Step in the Sensing Object

Threshold must be 

set to an absolute height.

       Acurate measurement 

is impossible.

With zero

 The height of the step is always 

evaluated in comparison to
