The introductory part of the paper explains the term surface roughness and describes 2D roughness parameters, in more detail those measured in the experimental part of the paper. After that, the measuring stylus devices are described; their general configuration and the ways to guide the probe. Mistakes that may occur when measuring with stylus device are listed. A Perthometer S8P measuring device is especially described because it was used for measurements in the experimental part of the project. An upgrade of the Perthometer S8P measuring device is proposed to ensure the accuracy of the positioning of the measuring needle of the stylus mesauring device. Upgrade elements (camera and translational elements) are described and their technical specifications are listed. Afterwards it is stated how these upgrade elements are connected to the roughness measuring device to provide the required rigidity to the system. The method of determining the position of the measuring traces on the sample and the way of calculating the coordinates of the initial measuring points on the measuring surface of the standard are described in detail. The influence of the dimensions of the measuring surface of the roughness standard and the influence of the required cut-off on the arrangement of measuring traces on the measuring surface is described. Four different ways of distributing measuring traces on the measuring surface are proposed given the limitations. The standards that were used for the measurement were then selected. According to their dimensions and the required cut-off, suitable arrangements of the measuring traces on the measuring surface were selected for each of the standards and the coordinates of the initial measuring points were calculated. Paper then describes how the position of the measuring needle, the position of the camera's cross, and the position of the translational elements were brought into the relationship via measured roughness standard. After connecting these three elements, the standard moved with translational elements to the positions of the starting points and trace measurements were carried out on the measurement surface of the standard. The measurement results are presented graphically and numerically. Obtained results were then commented.
