GIVI MEASURE CHARACTERISTICS RESOLUTION AND ACCURACY The resolution of the scales depends on the grating pitch, by the conversion factor of the digital signals and by the discrimination of the Accuracy counting unit. If the conversion factor required is, the electronic of the impulses generation is already in the transducer. Differently, it is necessary to use the external interface DVX ask for relative documentation. The accuracy of the scale is shown by the characteristics of the single model. The dimensional test certifies that in any position, the deviation between the absolute measuring LA and the relative one LR, that is the error E, is always within the specifications.
