The measurement of the resistivity of metals has developed rapidly in the last decade, by measuring the voltage generated across a conductor when a certain current flows through it, according to ohm's law, the resistance of the conductor, which is related to the shape of the material, changes with the length and cross-sectional area of the material under otherwise constant conditions. Currently, contact-type metal resistivity meters work by measuring the voltage between the contact points to determine the resistance of each part while passing a constant current, and then determining the contact resistivity according to a corresponding model. Thus, with respect to the resistivity measuring clamp body, which is the resistivity measuring instrument introduced into the shape of the material, an important component of the length and cross-sectional area of the material is determined.
