The necessity of reducing the gap between levels of measurement accuracy in engineering and basic science research is consideret.

The metrological reliability problems of the digital technologies use in fields loads and technical condition multi-channel monitoring systems of three-dimensional objects spatial constructions are considered, as well as similar regularities of the amplitude and phase distortions phantom manifestation in project and scientific modeling with the use of widely used software complexes.

In the context of nonlocality of the impact on the quantum object the features of pulsed magnetic disturbance emission in the closed superconducting slit UHF transmission line are analyzed. It is suggested that in contrast to the experiments already conducted with photons this approach allows to specify the result of nonlocality impact in simpler situation with the only one component of electromagnetic radiation.

The classification of hardware used during measurements, studies, tests and control is suggested. The possible forms of conformity assessment and the regulatory support of the above procedures are considered.

The results of experimental study of reliability of the digital information transfer depending on the noise level in communication channel are presented. The measurements are carried out for the standard MODBAS-like exchange protocol protected from distortions by means of cyclic control CRC sum. The conditions of occurrence and the size of information exchange errors in transmitted information are estimated.
