Overlay:
grey: Profile in the respective direction of integration
blue: Gradients from the above profiles
yellow: Result of the geometric filter
red: Interpolation limits for determining position
light blue: Result of interpolation -> position
Comments:
The interpolation result should be found around the maximum of the geometric filter.
Cross:
white: Result of position recognition -> x, y, angle
Diagram:
Result function of the angle search (rotating windows).
Comments:
The minimum (corresponds to the maximum of the sum of the gradients) gives the non-interpolated
relative position. The final result (through interpolation) is displayed by a light blue line. The accuracy
of the diagram is limited by the resolution of the monitor.
2. Row-Driven Mode
See Section 7.6.5.2 from page 7 - 95 for a definition of the measuring methods.
This measurement mode can be recognized by a number of windows around the middle pins of a row of pins.
Procedure:
I. Position recognition takes place via the formation of profile vertical to the direction of the pins. This is used
to determine the edges of the component.
II. With two additional windows the relative position of the component can be determined.
Rectangles:
green: x and y location tolerances
light blue: A. 2 to 4 search windows for position recognition. These are located around the middle
pins of each pin row.
B. 2 Additional search windows for angle measurement. Both windows lie in the same pin
row.
Star:
orange: Result of the first scan procedure
Comments:
The star indicates the position in the pin direction. Depending on the measurement algorithm used the
middle or the tip of the pin will be displayed.

3. Corner-Driven Mode
See Section 7.6.5.2 from page 7 - 95 for a definition of the measuring methods.
This measurement mode can be recognized by the windows around the entire pin row.
Procedure:
●
Determine the position in the direction of pins in the light blue window
●
Determine the position vertically to this in the dark blue window
●
Calculate the position of each pin group and thus of the component
Rectangles:
light blue: Search window for the position in the direction of pins
dark blue: Search window for the position vertically to this
green: x and y tolerances
Star:
orange: Result Location of the group concerned
Comments:
Depending on the measurement algorithm selected the middle or the tip of the pin group in the direc-
tion of pins will be displayed.
Cross:
white: Result of position recognition -> x, y, angle
Overlays:
grey: Profile in the integration direction concerned
blue: Gradients from the above profiles
yellow: Result of the geometric filter
red: Interpolation limits for position determination
light blue: Result of interpolation -> position
Comments:
The overlay is provided both for the light blue as for the dark blue search windows.

4. Lead-Driven Mode
See Section 7.6.5.2 from page 7 - 95 for a definition of the measuring methods.
This method can be recognized by there being
–
either a window around a lead group (combined window, preset value)
–
or a window around each individual lead (separate window). You can modify the "separate" or "combined"
window type under the "Change measure mode" menu by entering the hex code.
Procedure:
Each lead is measured individually, as in corner-driven mode, or the entire lead group is measured.
Rectangles:
dark blue: Search windows around every pin of a group
light blue: Search windows around the first pin of a group
green: x and y tolerances
Cross:
white: Result of position recognition -> x, y, angle
Overlay:
grey: Profile in the integration direction concerned
blue: Gradients from the above profiles (the gradients are only displayed and required for the
profile in the direction of pins).
yellow: Result of the geometric filter
red: Interpolation limits for position determination
light blue: Result of interpolation -> Position
Comments:
An overlay is offered for both directions of integration.
