Option

With this option you can change the ball model description.

Use the tabulator key to select the ball model.

With the spacebar select the radius type - inner or outer radius.

Use the arrow keys to enlarge or reduce the internal or external radius of the ball. The balls will be dis-

played 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).

Use the

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.

With the Return key you can trigger the individual measurement steps which are specified in the measure-

ment conditions for the specified component.

Press Esc to cancel the option, even if not all measurement steps have been carried out. You will then be

returned to the Test component menu.

You can select the following parameters:

– Number of sections which contain the transformation table: number between 1 and 5

– Selection of value pairs: with 5 sections 10 pairs of values are permitted.

Numerical presentation of the table

The numerical values are indicated in the upper part of the option box. These are:

Section: Number of sections

OUT Begin: OUT End: Ranges of values for the transformation of the individual sections

IN: Range limits of the individual sections

Graphic presentation of the table

In the diagram

– 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

– Accept

Click on the

button to save the settings. The option box will then close.

– Cancel

With

Cancel

you can discard the settings. The option box will then close.

– Help

With the

Help

button you can access explanatory material regarding the on-screen presentation.

– Number

input field

You can choose the number of sections

by entering the numerical value directly into the display field, or

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

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

– 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 transforma-

tion line and the numerical value will be displayed at

OUT Begin

OUT End

– Selecting the section limits

The graphical representation in Fig. 5.6.30, Page 5 - 109 shows 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:

– Once you have programmed your transformation table you can quit the option box by clicking on

Cancel

Notes on using the transformation tables to set the contrast sensitivity

– Select up to 3 sections.

– The range of values for the individual sections should be at least 75.

– Program the ranges so that no jumps occur at the range limits.

Set the contrast sensitivity so that the shape of the curve roughly corresponds to one of the three following

examples:
