Double electric digital four probe tester is used to measure two bits of a straight line or square four probe.The instrument is designed to meet the national standards of the single-crystal silicon physical test method and the American A.S.T.M standard.Using transformation of current probe and voltage probe to process two electric measurement. Double electrical analysis of data.automatically eliminate the sample geometry size and boundary effect and probe not equidistant and moving machinery. such as the factors influence on the measured results. Compared with the single electrical measuring linear or square four probe. greatly improve the accuracy. Especially suitable for diagonal four probe for micro area of the test.
