Abstract��Methods for strain��measurement of maximum bending strain for rectangular cross��sectional specimen are generally more used in a four��point measurement, but the three��point measurement approach also has its advantages. Since it has three measurement channels, the structure is greatly simplified, so that it is relatively simple to realize automation. Through the derivation, calculation formula for the three��point measurement approach have errors in appendix B of GB/T1040.4��2006 and ISO527��4:1997��
