The most favorable construction of the yoke of a single sheet tester has been studied by measurements and numerical analysis. It is shown that the eddy currents in a specimen affect the measurement error of the single sheet tester, and the error is increased with increase in the overhang length and with decrease in the distance between yokes. It is concluded that the single yoke type tester has a large error due to eddy currents, and the double yoke type tester is more favorable.
