4.2 Calibration of Presetter

4.2.1 Set the camera’s working distance

The working distance is defined as the distance between the front edge of the cam-

era tube shield and the object to be measured, for example a tool cutting edge.

This measurement is preset by the design and the production tolerances of the cam-

era tube shield (lens).

The working distance must be set following the instructions in the

enclosed calibration log with a permissible tolerance of 100 ±

0.1mm. (3.937 ± .004”)
