The following combinations of measurement methods are used:
– Size-driven — corner-driven — lead-driven (see table in Section 6.6.4.15) or
– Row-driven — corner-driven — lead-driven (see table in Section 6.6.4.15)

The measurement results will provide information on the approximate coordinates and approx-
imate rotation of the component. In addition, you will be informed of the quality of measure-
ment.
– The measurement results will provide precise information on the approximate coordinates and
approximate rotation of the component. In addition, you will be informed of the maximum ball
offset and the quality of measurement.

The following table contains our recommendations for the optimum sequence of measurement
methods for particular components. The following abbreviations are used:
B = ball-driven C = corner-driven G = grid-driven
L = lead-driven R = row-driven S = size-driven

In this measuring mode, if the component rotation has been calculated incorrectly on account of
ambiguity, you can increase the angular resolution in order to determine the angle of rotation. The
following increments may be used in relation to the resolution in order to determine the angle of
the components:
– Low resolution:
– Medium resolution
Determining the angle every 4° within the angular tolerance
– High resolution
Determining the angle every 2° within the angular tolerance
– Very high resolution
Determining the angle every 1° within the angular tolerance

Here you must specify the number of rotation windows in order to determine the angle:
– Automatic selection
The system selects the number of windows.
– SWIN method (Single Window)
Selects a single window. This method is suitable for small components and fluctuating dimen-
sions.
