This diploma thesis Length measuring instrument check describes and introduces most frequntly used tools for lenght measurment in metal working industry, such as caliperes, indicators and mikrometers. I presented both digital and analog tools for lenght meauserment.
In the theoretical part of the thesis I described how the digital measuring tools work and which component they are made of. Capacitive sensors are briefly described with two configurations of the layout of the electrodes, which directly detect movement.
Below I described length measuring instrument check instructions. In the practical part I presented a concrete example of calibration a table. The results of the measurements in the final part of the thesis show that by meausiring the table and using a linear correction I improved the accuracy of measurements.
