FIELD: electricity.
SUBSTANCE: probe is brought together with surface of conductive substance in liquid condition, which properly soaks probe material and conductive coat applied on conductive substrate. Electric voltage is applied between substrate and probe, which is varied so that electric current values that correspond to more than three values of applied electric voltage are validly registered. Procedure of submersion is terminated, when registered non-zero electric current within the limits of experimental error becomes proportional to applied voltage, afterwards probe is withdrawn from conductive substance in liquid condition. As a result of this, probe tip becomes coated with conductive substance in liquid condition. Drying of produced layer results in formation of smooth surface.
EFFECT: production of stable electric contact of probe with investigated surface, provision of high stability and repeatability of electric measurements.
