Abstract: Research on the formation peculiarities of the random error-component while measuring electric noise has been undertaken. The parameters of interaction between the researched substance and a measuring probe including energetic and time parameters are enlightened. The latter are balanced with relaxation time, period prior to performed gauge and duration of measuring. The problems of activity / passivity of the measurement method and features of studied object reaction are under consideration. It is proved that the nature of relaxation is determined by a fluctuation-dissipation mechanism of forming electric noise of an object and consequently their undertones (thermal noise or/and 1/f noise). The followed issue is the inexactness of the summary results of repeatable measurements, and stiffness of the random error to reduction by averaging.
