Points marked with a red + sign:
outside the circle:
Contrast < 0, ball is darker than the background
inside the circle:
Contrast > 0, ball is brighter than the background
Points marked with a yellow – sign:
The separation between “+” and “–” characters represents
the radius tolerance.
2. Ball-Driven Mode
See
Section 7.6.5.2 from page 7 - 95
for a definition of the measuring methods.
The method works with high precision and is thus suitable for precisely determining the position of all defined
balls.
Ball-driven mode as a precise search follows grid-driven mode.
The measuring methods can be recognized by
–
the synthetic representation of the model in pixel resolution at the lefthand edge of the video screen
–
there being a window around each ball (separate window) or
–
depending on memory, there being one window over the entire component or one defined row of balls
(combined window).
Procedure:
All of the balls defined in the GF file are gauged. The selection of window mode will be based on geometrical
criteria:
–
If the distance between two balls is low (< 2 x ball diameters), the "combined" window mode will be pre-
ferred.
–
If the ball separation is larger, the "separate" window mode will be chosen. The default mode is the sepa-
rate window.
Window:
Dark-blue: over one ball in each case (separate window)
over one row or all of the balls (combined window)

7.6.3.5 Option “Test component”
NOTE
This option can only be activated if a GF number has already been entered.
If a component is not optically centered, you have the choice of checking the centering procedure with this
option. The measurement result is presented visually on the screen; measurement results are not saved.
Fig. 7.6.11
When this function is activated the following actions are initiated:
–
The measuring procedure is activated.
–
The video image is displayed on the screen.
–
Top and bottom lines appear.
