11. - Changing/Setting Threshold fi lters
- 1. Press the “Change parameters” tab above the centre screen.
The centre screen will now show the Threshold fi lter(s) for the selected device (see picture).
Attention: - None of the changes made in this menu will have any effect on the sorting
process as long as the “Use parameters” button is not pressed!
- 2. Setting the 2D Defect Size and Defect Density (Fill rate) percentage.
- 2D Defect Size
In general it is advisable to set the Defect width and Defect length in such a way that the 2D
defect dimensions form a square. Usually +/- 1 x 1 mm for smaller products and larger dimensions
for bigger products or for specifi c defects (see picture above).
(Remember! To see the actual dimensions the belt must be running)
- Defect Density
This is usually simply left at 100%, but in certain specifi c cases it may be lowered to allow for
small spots (see chapter 3: Theory).
