4.2 Calibration of Presetter<br />

4.2.1 Set the camera’s working distance<br />

The working distance is defined as the distance between the front edge of the camera<br />

tube shield and the object to be measured, for example a tool cutting edge.<br />

This measurement is preset by the design and the production tolerances of the camera<br />

tube shield (lens).<br />

The working distance must be set following the instructions in the<br />

enclosed calibration log with a permissible tolerance of 100 ±<br />

0.1mm. (3.937 ± .004”)<br />
