È Use the tabulator key to select the ball model.
È With the spacebar select the radius type - inner or outer radius.
È Use the arrow keys to enlarge or reduce the internal or external radius of the ball. The balls will
be displayed in their geometric dimensions as a pixel image on the lefthand edge of the video
image.
The value of the inner radius the ball shape:
– If the inner radius is equal to 0, the ball will take the form of a circle.
– If the inner radius is greater than 0, the ball will take the form of a doughnut (not frequently
used).
È Use the + or - keys to increase or reduce the ball contrast.
Select ball contrast > 0, if the ball is lighter than the background.
Select ball contrast < 0, if the ball is darker than the background.
È With the Return key you can trigger the individual measurement steps which are specified in
the measurement conditions for the specified component.

Graphic presentation of the table 6
In the diagram 6
– the abscissae (x axis) represent the input values range, subdivided into sections.
– the ordinates (y axis) represent the output values with their color allocation.
Buttons 6
È Accept
Click on the Accept button to save the settings. The option box will then close.
È Cancel
With Cancel you can discard the settings. The option box will then close.
È Help
With the Help button you can access explanatory material regarding the on-screen presenta-
tion.
È Number input field
You can choose the number of sections
È by entering the numerical value directly into the display field, or
È by moving the scroll field in the scroll bar to the right or left using the mouse. In this way you
can run back and forth through the values range (1 - 5), or
È by clicking on the lefthand or right-hand arrow on the scroll bar. In this way you can increase
or decrease the number of selections.
Programming the transformation table 6
È Specifying the output values
Position the mouse pointer over the ends of the transformation lines of each section. The ends
are marked with small horizontal lines. A vertical double arrow will then appear on the screen.
Click on the lefthand mouse key and move the arrow upwards or downwards. This will move
the selected end of the transformation line and the numerical value will be displayed at OUT
Begin or OUT End.
È Selecting the section limits
The graphical representation in Fig. 6.6 - 30 on page 266 shows equidistant section limits with
the ranges 0 - 80, 81 - 180 and so on. You can change these section limits if you wish. However
limits 0 and 255 are permanently allocated and cannot therefore be moved.
Position the mouse pointer on a section limit (but not 0 and 255). A horizontal double arrow will
appear on the screen. Hold down the lefthand mouse pointer and use it to drag the section limit
in the direction you want. The corresponding numerical value will be displayed at IN:.
È Once you have programmed your transformation table you can quit the option box by clicking
on Accept or Cancel.
