If the tab Exp. Magnets is selected a list of the available magnets will appear on a table. By clicking one of the magnets, its "demand" value can be changed in the text-editing field. Depending on the reaction speed of the magnet power supply, the measured value will eventually reflect the new "demanded" value.

Example of the dialog window to modify the field of a device. By clicking on the desired magnet in the table, the new demand value can be entered in the text-editing field.
