The new method of the high-fidelity measuring of resistances was proposed. A Wheatstone bridge was used with two unknown base resistors of R1 and R2 in one branch, the resistance decade boxes and unknown resistance Rx was plugged in other branch. By the selection of Rm1 of resistance decade boxes bridge was balanced. R1 and R2 switched places then. By the selection of Rm2 of resistance decade boxes the bridge was balanced in second times. Unknown resistance settled accounts on the formula of Rx=(Rm1•Rm2)1/2.
