| 1. A measuring arrangement comprising:
a support;
a scale comprising:
a measuring graduation; and
an electrically non-conductive substrate selected from the group consisting of glass and a glass-ceramic material, wherein
said scale is fixed on said support by a mounting force generated via electrostatic clamping by a plurality of electrodes,
wherein said measuring graduation is situated on one side of said substrate and one of said plurality of electrodes is provided
on a surface of another side of said substrate situated directly opposite said measuring graduation, wherein said one of said
plurality of electrodes is made of a coating of an electrically-conducting material, and wherein said electrostatic clamping
occurs on said surface of said scale situated directly opposite said measuring graduation.
