Abstract

A surface texture measurement device capable of resolving errors for each entire display range, a controller for the surface texture measurement device, and a method for controlling the surface texture measurement device that includes selecting any one of the display ranges as a reference range and defining a calibration measurement value for each display range; sequentially inputting the calibration measurement values in place of the measurement values to the range amplifier corresponding to the reference range to obtain a reference display value rDATAi; inputting the calibration measurement values to the range amplifiers corresponding to each display range, then obtaining an AD-converted value ADi and a display value DATAi; computing a gain error rate ki = rDATAi / DATAi, a display resolution DIVi = DATAi / ADi, and a corrected display resolution cDIVi = DIViXki; and displaying the corrected display value cDIVi = DIViXki.

Description

technical field [0001] The present invention relates to a surface texture measuring device, a controller for the surface texture measuring device, and a method for controlling the surface texture measuring device. Further, the present invention relates to a surface texture measuring device having a plurality of display ranges, and a method for controlling the surface texture measuring device. Background technique [0002] In general, surface texture measuring devices are known to scan the surface of a workpiece by means of a probe to measure its surface texture (surface roughness, undulations, topography, etc.). In the surface texture measurement equipment, the probe moves in a fixed direction (X-axis direction), and is displaced in the vertical direction of the probe (Z-axis direction) due to the unevenness of the workpiece surface. The detection signal is amplified or AD conversion is performed, and then the signal is displayed on the display as a function of the moving d...
