7.7.3 Shapes and possible measuring methods for rough (G) and fine
centering (F)
*) LEAD with combined evaluation windows for each row of pins replaces the CORNER measuring method.
Measurement of the spacing is replaced by measurement of the (standardized) lead deviation.
If one or more of the results are outside the tolerance,
the component will not be inserted.
If the component cannot be centered correctly, additional measuring methods may be omitted. You should,
however, carry out all the rough centering steps since these reduce the size of the measuring window.
–
In the ’Test component’ menu, the components are optically centered in the individual measuring steps, via
the ’Check component’ function, but the results are not output.

If the components are larger than 32 mm x 32 mm, a multiple measurement will be carried out automati-
cally in the vision system.
7.7.4 Test Package Form - Visual Representation / Programming Mea-
surement Types
–
In the ’Test component’ menu, a component is picked up and then moved to the camera and mapped in its
0° position. The component is displayed with respect to its insertion angle at the revolver head of the S-15/
F3.
