You must follow the steps below:
1. The background color of the scanning screen and its size are the same as those of the Hess test scanning screen, so you do not need to set them.
2. Set the scan distance (1).
If you want the distance to be such that the scanning field extends 70° per quadrant, press the "Calculate" button (2).
3. Set the size of the token (3).
You can vary the width and height if you have chosen a rectangular token or the radius if you have chosen a circular token.
If "Adjust to scanning distance" is selected, the size is adjusted to the scanning distance, so that the surface is proportional to the scanning distance.
4. Press "Calculate" if you wish to adjust the size automatically (4).
5. Select "Adjust to scanning distance" if you want the size of the core to be adjusted to the scanning distance, so that the surface is proportional (5).
6. Guides size selector according to Goldmann patterns (6).
7. Selector to change the shape of the core, which can be rectangular or circular (7).
8. Selector of the color of the core, by default white (8).
