In this paper shown that the means of measuring the parameters of mechanical defects that are currently used or obsolete, or not fully meet modern requirements, or to use them requires significant adaptation to the characteristics of the generator. These problems largely determine the need for new types of computerized parameters meter mechanical defects powerful generators of opto-electronic elements. It is shown computerized measuring instruments is necessary to consider that generators are powerful sources of industrial frequency magnetic radiation, which literally penetrate the entire internal volume of the generator, present in separate points of the engine room and even the surrounding areas. Measuring parameters of mechanical defects, work on power requirements are quite high and they should be resistant to the effects of industrial frequency magnetic field strength of 30 A / m functioning quality criterion A. The results of experimental studies of the influence of the magnetic field of an industrial frequency on the stability of the functioning of a microcontroller are presented. The latter is intended for the development of new types of computerized meters for the parameters of mechanical defects of powerful generators with optoelectronic elements that can operate under strong magnetic fields of industrial frequency. The special stand and corresponding testing algorithms have been developed and used for experimental research. The experimental results obtained for calculating the dependence of the parameters of the induction value in the air gap of the test core of the stand from the alternating voltage applied to it. It is established that the introduction of Cortex-M0 microcontroller in a magnetic field with magnitude of magnetic induction from 0.1 to 0.6 T does not affect the stability of its functioning by functioning quality criterion A.
