Diagram:
Results function of the angle search (rotating windows).
Comments:
The minimum (corresponds to the maximum of the sum of the gradients) indicates the non-
interpolated angular position. The final results (via interpolation) are indicated by a light blue
line. The precision of the diagram is limited by the resolution of the monitor.
2. Row-driven mode
See Section 6.6.4.14 on page 6 - 281 for a definition of the measuring methods.
You can recognize this measurement method by the presence of windows around the central lead
of a row of leads.
Procedure:
(1) Position recognition takes place by creating a profile vertical to the direction of the leads. In
this way the edges of the component are determined.
(2) With two additional windows the angular position of the component can be determined.
Rectangles:
green: x and y pick-up tolerances
light blue: $ 2 to 4 search windows for position recognition. These are positioned
around the central lead of each row of leads.
% 2 additional search windows for angular measurement. The two
windows are located on the same row of leads.
Star:
orange: Results of approximate search
Comments:
The star indicates the position in the direction of the leads. Depending on which measure-
ment algorithm has been selected the middle or the tip of the lead will be displayed.

See Section 6.6.4.14 on page 6 - 281 for a definition of the measuring methods.
This measurement method can be recognized by the windows around the entire row of leads.
Procedure:
Å Determine the position in the direction of the leads in the light blue window
Å Determine the position vertically to this in the dark blue window
Å Calculate the position of each lead group and thus of the component
Rectangles:
light blue: Search window for the position in the direction of the leads
dark blue: Search window for the position vertically to this
green: x and y tolerances
Star:
orange: Results: Location of the group in question
Comments:
Depending on which measurement algorithm was selected the middle or the end of the lead
group in the direction of the leads will be shown.

/HDGGULYHQPRGH
See Section 6.6.4.14 on page 6 - 281 for a definition of the measuring methods.
This measurement method can be recognized by
– either there being a window around a leads group (combined window, preset value)
– or there being a window around every single lead (separate window). By entering the hex code
you can modify the window types VHSDUDWH or FRPELQHG ZLQGRZ in the 0HDVXUHPRGH
menu.
Procedure:
Each lead will be measured in a way similar to corner-driven mode or the entire leads group will
be measured.
Rectangles:
dark blue: search window around the entire leads group or around every
light blue: search window around the first lead in a group
green: x and y tolerances
Cross:
white: Results of position recognition -> x and y angles
Overlay:
gray: Profile in the integration direction in question
blue: Gradients from the above profiles
The gradients are only required and displayed for the profiles in the
direction of the leads.
