Digital measuring probes

The incremental measuring method in digital probes is based on the division of a homogeneous grid structure. Here, the position of the probe is obtained by counting individual increments (also called measuring steps), whereby the zero point (start of counting) can be set as desired. In order for this position information to have an absolute reference, there is another track on the measuring standard which carries a reference mark. This reference mark, which determines an absolute position of the scale, is assigned to exactly one signal period. Only by passing over the reference mark can an absolute reference of the position be established or the last defined reference point be approached again.
