FIELD: measuring instruments.
SUBSTANCE: method includes determining conventional hardness for several reference measures and input them together with corresponding nominal values of hardness into the instrument computer memory. The data are used for determining a function by the method of least squares. The function has the form HV=a0+a1HL+a2HL2+…+anHLn, where HV is the Vickers hardness scale, HL is the conventional hardness, a0, a1,…, an are the coefficients of a polynomial, and n is the power extent providing required accuracy of measurements.
EFFECT: enhanced accuracy.
