Measuring system in which all position (or angle) information is referred to a common zero point. Every point on the measured path is identified by a unique signal. Measuring systems that can be used:

Accuracy with which a pointer instrument indicates. It is generally defined in accuracy classes. Here it is important to state whether the accuracy relates to the permissible error limits on the value

Range of measured values that can be read on a measuring instrument. This range is not necessarily identical to the measuring range .

A programming language for programmable logic controllers (PLC) in which the control functions are listed in the form of statements. The statement list is internationally standardised in IEC 1131-3.
