FIELD: computer engineering. SUBSTANCE: device has memory unit, at least one unit for conversion of small values of object characteristics, which is connected to one output of memory unit. digital-to-analog converters are connected to other outputs of memory unit and to output of unit of conversion of small values of object characteristics. Outputs of digital-to-analog converters are connected to units for generation of outline two-dimensional shapes. Serial circuit, which contains unit for generation of combinations of outline two-dimensional shapes and visualization unit are connected to said units for generation of outline two- dimensional shapes. User interface unit is connected to visualization unit. User interface unit provides possibility for operator to interact with visualization unit. Device provides possibility to monitor object state during all operations of object instead of pre-determined transition modes. EFFECT: increased sensitivity to early indications of object faults, increased resolution, increased functional capabilities. 4 dwg
