Page 14: Technical Data
KITL-Series Technical Data Resolution and Accuracy (Definition) Basically one has to differentiate between the resolution and the accuracy of a measuring system. The two parameters are not directly interdependent and may differ from each other. Resolution The resolution of linear system describes the least possible displacement of scanning head against the scale which can still be discerned by the evaluation electronics (display, control). It depends on (see chart 1) • the graduation period of the scale • the signal intepolation factor (internally or in auxiliary electronic unit) • the evaluation mode in the counter Accuracy The accuracy of linear measuring systems is specified in accuracy classes. -
