Abstract—A setup for determining the contact electrical resistance measured using two surface point potential probes installed at the same distance from the contact surface is described. The total number of paired probes located at different distances from the contact surface is four. The reference temperature range is 380–1500 K. Measurements can be performed in vacuum and in air. The setup allows one to investigate the contact resistance at a direct current, which may vary from 20 to 120 A. The first test experiments have shown that changing the current polarity does not affect the current–voltage characteristic measured on a monolithic sample or on a sample with one fixed contact surface.
期刊介绍：
Instruments and Experimental Techniques is an international peer reviewed journal that publishes reviews describing advanced methods for physical measurements and techniques and original articles that present techniques for physical measurements, principles of operation, design, methods of application, and analysis of the operation of physical instruments used in all fields of experimental physics and when conducting measurements using physical methods and instruments in astronomy, natural sciences, chemistry, biology, medicine, and ecology.
