構。 A variable load means that can arbitrarily change the load by changing the amount of current, an indenter that is pushed into the sample surface when the load of the load means or the load of a test weight is applied, and the indenter. displacement detection means for detecting the displacement of the indenter; means for calculating the load acting on the indenter from the amount of current supplied to the variable load means; and means for outputting a load corresponding to the weight of the test weight. Compare the displacement of the indenter obtained when a current is supplied to the load means with the displacement of the indenter when a test weight is actually loaded, and calculate the amount of current supplied to the load means necessary to make the two match. A load verification mechanism for a hardness tester, comprising a calculation means for calculating the difference between the actual load of a loading means and the weight of a verification weight from an increase/decrease.
