MEASUREMENT APPARATUS FOR THE ABSOLUTE DETERMINATION OF LENGTHS AND OF ANGLES
First Claim
1. A measurement apparatus (10) for the absolute value determination of lengths or of angles, said apparatus having at least one reading head (14) and a physical scale (12) which has at least a partial section (18) with a connection (28) for another partial section (18) in a sequential arrangement, wherein the partial section (18) includes a control unit (30) for the active determination of the position of the reading head (14) proximal to the partial section (18) as well as a storage element (32) in which an own position information of the partial section (18) within the physical scale (12) can be stored.

Abstract
A measurement apparatus (10) for the absolute value determination of lengths or of angles, said apparatus having at least one reading head (14) and a physical scale (12) is provided, which has at least a partial section (18) with a connection (28) for another partial section (18) in a sequential arrangement. In this respect the partial section (18) includes a control unit (30) for the active determination of the position of the reading head (14) proximal to the partial section (18) as well as a storage element (32) in which an own position information of the partial section (18) within the physical scale (12) can be stored.

- 14. A method for the absolute value determination of lengths or of angles having at least one reading head (14) and a physical scale (12) which is formed from a sequential arrangement of partial sections (18), wherein a partial section (18) actively measures the position of the reading head (14) proximal to the partial section (18), wherein the position of the partial section (18) within the sequential arrangement is determined by means of a position information stored in the partial section (18) and wherein the absolute value is determined from the position within the partial section (18) and the position of the partial section (18) within the sequential arrangement.
