SX1934C four-point probe can measure resistivity of thin film material, as well as diffusion layers. The four
probes are arranged in a linear fashion, where the two outer probes are connected to current supply, and the
inner probes to a voltage meter, As current flows between the outer probes, the voltage drop across the inner
probes is measured.
