Reduction of Influence Factors

Any measurement system has imperfections and any act of measurement is liable to errors. Measurement errors either originate from system deficiencies (for instance system noise, quantization, and drift), or are due to environmental influences such as thermal, electromagnetic, and mechanical interference. Manufacturers of measuring instruments try to minimize such intrinsic errors by a proper design of the instrument structure; the remaining imperfections should be given in the data sheets of the system. The user of a measurement system should minimize additional errors that could arise from improper use and faulty interfacing
