Abstract

Some embodiments of the invention include a capacitive linear encoder for determining positions comprising a scale and a read head for capacitively scanning the scale, wherein scale and read head are movable relative to one another. The scale has at least one, preferably capacitive, position reference marker. On the basis of the position references provided by the capacitive position reference marker, the positions are locatable in absolute terms and verifiable.
