This paper presents an assessment of the force meter (dynamometer) dynamic accuracy applied in the engineering industry. This assessment was made by determining the dynamic error based on the absolute error criterion. The mathematical basis for determining the dynamometers error was presented, and the corresponding procedures were developed. The values of dynamometer parameters and associated uncertainties were determined, then they were compared with the values calculated in the corresponding datasheet and finally the relationship between the dynamic absolute error and the dynamometer parameters was presented. The solutions presented allow the easy and quick determination of the accuracy of the dynamometers, and first of all significantly an increase the reliability and safety of engineering systems which use these type of measuring devices. The upper bound of the dynamic error developed in the paper may constitute an additional comparative criterion in assessing the accuracy of dynamometers produced by different manufacturers. New achievement of this paper is the presentation of the relationship between the dynamic error expressed by using the absolute error criterion and the values of the parameters of the mathematical model of the dynamometer in terms of applications in the engineering industry. These relationships are presented using the corresponding mathematical functions as well as graphically using 3D graphs. The calculation results were obtained using MathCad 5.0 and MATLAB R2024.
