The phase error ψ at β = 0,65 – 0,70 almost linearly depends on the frequency, so the delay forced oscillations of the movable portion of changes in the measured value for each frequency in the same time.

Systematic errors arise naturally, so they can be quantified and excluded from the measurement results by amendments to the readings, numerically equal values of errors, taken with the opposite sign, or removed under the method of measurements.

Before processing the measurement results, they should be free from systematic errors.

Random error can not be predicted in advance and the likelihood of measurement errors of any sign about the same, they are volatile in absolute value. Therefore, unlike regular, random errors are eliminated and can not be excluded from the measurement results amendment. Their influence on outcomes measurement study methods of mathematical statistics and probability theory.

Subjective uncertainty arising from physiological characteristics tester, quality of work and experience.

Physiological characteristics observer related to his weight issues–ness, as of,. hearing and t. e., they are shown in the reaction rate signals while performing teams before the start and the end–metering in, blunders in reference records, and so on. n. Therefore, it is desirable that certain observations entrusted as possible, and one the same person.
