Abstract

Um eine Nachregelung von Betriebsparametern eines Gerätes in unzweckmäßige Bereiche zu verhindern oder wenigstens zu erschweren, wird die Nachregelung durch ein Werteintervall begrenzt, dessen Mittelwert sich dem momentanen Wert des Betriebsparameters anpaßt. Hierdurch wird besonders die Nachregelung von Betriebsparametern vereinfacht, die Veränderungen durch Alterung oder langsame Umwelteinflüsse unterliegen. Dies ist besonders dann von Vorteil, wenn die Nachregelung einen Betriebsparameter einer Anzeigeeinrichtung, z.B. die Versorgungsspannung eines farbigen LCD-Displays, betrifft, weil hierdurch in der Praxis verhindert wird, daß ein Benutzer die Anzeigeeinrichtung durch unsachgemäße Nachregelung unbrauchbar macht.
