Abstract

PURPOSE:To exactly push an indenter into a determined test position, and also, to efficiently execute an operation for starting a test, by providing the indenter on the center part of a sample surface observing lens of an optical monitor. CONSTITUTION:First of all, a sample 9 is fixed to a sample base 11 and positioned at the center of an objective lens 13. Subsequently, the sample base 11 is moved up and down, while peeping at an eyepiece 17, and when the surface of the sample 9 is found out, a position for a test is determined by operating a stage 10. Next, a current in the load direction is allowed to flow to an electromagnetic coil 5, a load generated in a load generating part is transferred 4, an objective lens holder 12 is lowered and an indenter 8 is pushed downward. As for a measurement controller 20, a test condition is determined in advance, and the test is advanced by a prescribed sequence. When no space exists between the tip of the indenter 8 and the surface of the sample 9, the tip of the indenter 8 makes a dimple on the surface. Also, when it is discriminated that no space exists, the distance in which the indenter 8 has moved from that time can be detected by a displacement detector 7, as the deformation quantity of the sample 9.
