Resistance Measurements
Three- and Four-Point Method, Test Methods, Four-Point Resistance Measurements, Ohmmeter measurements are normally made with just a two-point measurement method., The four-point resistance measurement method eliminates lead resistance. Instruments based on the four-point, measurement work on the following principle
