Methods for Selection of Measuring Instruments

One of the tasks at planning of quality inspection is selection of measuring instruments. The measuring instruments are the most important part of the measuring process so their selection have to be done carefully. The selection of measuring instruments is a complex task, which depend on the size, the character and the value of measured magnitude. The purpose of this paper is to analyze the existing methods for selection of measuring equipment. In the paper are presented the advantages and disadvantages of existing methods and recommendation for their implementation, according to the metrological tasks given. There are results obtained, using the Measurement System Analysis (MSA), for: selection of the correct measuring instrument and method; assessment the capabilities of measuring instruments; assessment of the procedures and operators; assessment of any measuring interactions, calculating the uncertainty of measuring of individual measuring instrument and/or measuring systems.
