Abstract
This paper considers an analog circuit providing automatic setting of the scale coefficient from the zero value of the difference current. The main difficulty arising in implementing such a circuit is associated with the controlled dc divider, which determines the metrological parameters of the entire circuit. In the proposed circuit for setting the scale factor automatically in a constant-current difference polarograph, a 525 PS2 analog multiplier was employed.
