Abstract
The invention relates to an invention for compensating for play in a measuring system in which a measuring arrangement is connected via a mechanical transmission system to a body, the movement of which is to be measured, and in which the measuring result is processed in an electric signal processing unit. The moveable body is provided with a friction coupling and a friction rod extends through the friction coupling. The rod is provided with a stationarily mounted arrangement which counteracts movement of the friction element and detects the occurrence of a counteracting force. This force can be detected electrically. The signal processing unit has a control input which is connected for sensing the arrangement and processes solely signals obtained from the measuring arrangement when a counteracting force is detected.
