OBJECT OF THE INVENTION A method of checking live resistive electrical circuit resistive devices is to provide a DC current measurement to a sample DC resistor of a controlled device, to determine a sample gauge and a baseline error control. characterized in that, in order to increase the accuracy of the alternating current control, a direct current measuring current equal to the current supplied to the sample gauge is supplied from the auxiliary device to an electric circuit that is under voltage of the working alternating current , the output of the auxiliary device divides the alternating component of the voltage that is applied to the output voltage of the controlled device, according to the value of the output voltage of the controlled device, the resistance of the sample gauge and the basic error of the controlled device are determined * 260956
