Date Jul. 10, 1980.A device for manufacturing resistors from insulated wire comprises a mechanism for taking up a wire unwound from a resistor being manufactured, the resistor being installed in a securing mechanism. Current output and input electrodes provide resistive and capacitive coupling between the unwound wire, a measuring circuit and a harmonic generator. An emitter follower is connected via its potential input to the electric contact element of the securing mechanism and via its output to the potential input of a phase-inverting amplifier whose output is loaded into a clamping amplifier. A precision voltage divider has one of its poles connected through a reference resistor to the electric contact element of the takeup mechanism. A common tap of the precision divider and the electric contact element are connected to a phase-sensitive indicator through a differential amplifier having a high-resistance input, the reference-signal inputs of said phase-sensitive indicator being coupled to the outputs of the clamping amplifier, while the output thereof is connected through a con
