Calibration method to assess the accuracy of measurement devices using the theory of uncertainty

Abstract

Abstract. The development of evaluation methods for precision measurement and inter-verification interval measurement for measurement devices based on the concept of the uncertainty of measurement is needed in order to establish the timing of the next scheduled or unscheduled verification of the correspondence of metrological characteristics to their standardised values. The definition of the timing (periodicity) of the metrological verification of measurement devices as used in business or health care, while monitoring environmental conditions and proving health and safety at work, is an urgent issue in scientific research, upon which depends the quality of goods and services. A method of evaluating the accuracy of measurements and the inter-verification interval for measurement devices is proposed, based on using international standards guidelines for quality measurement. The calibration method for evaluating the inter-verification interval of measurement devices was tested during the metrological certification of the measurement device for the moment of inertia of electric motors.

Evaluation of uncertainty in the measurement of sense of natural language constructions

“…Thus, for an arbitrary sequence 〈i l , i j 〉 the value Y = m Q (〈i l , i j 〉) as measured according to (3), is functionally dependent on the results of repeated measurements X 1 , X 2 , …, X N for different ACSs and, in general, is as follows:…”

“…Formally, this can be done in various ways, one of which is to assess the uncertainty of the measurement result of the sense of separate natural language constructions (NLC), the texts, and artificial cognitive systems (ACS) in general, at a given time. It is known [3] that the uncertainty of measurement is a parameter associated with measurement results, characterized by the dispersion of values that can be quite reasonably attributed to the measured value. But it is important that the value that is directly used to express uncertainty should be internally consistent, directly derived from that components that comprise it, and should not be dependent on the grouping of these components and their subdivision into sub-components [4].…”

A frequency method for dynamic uncertainty evaluation of measurement during modes of dynamic operation

“…As a rule, information on the dynamic characteristics of the measurement means can be located in the documentation accompanying such devices, although if such information is not available, it can obtained from the metrological certification of the measurement means or it may be determined a priori [5,11].…”

“…In producing reports on the results of dynamic measurement we must state the quantitative value of each experimental quality so that its reliability can be correctly assessed [1][2][3][4][5]. Without this value, the results obtained of dynamic measurement cannot be compared, and neither with analogous results obtained by leading laboratories around the world.…”

Metrological characteristics of the torque measurement of electric motors

“…As has been demonstrated in the relevant literature [4][5][6][7][8][9][10][11][12][13][14], the basic characteristics of MM include sensitivity, additive errors, multiplicative errors, measurement ranges, and primary and secondary errors (uncertainties) in the MM which in international scientific metrology practice is sometimes known as the Measurand Model. These characteristics are sufficient to establish standards for the accuracy of the MM [11,12].…”
