Measuring system and method for hardness measurement

A measuring system for hardness measurement of an object, the measuring system comprising:

• a stand having
• a base plate and a vertical column fastened thereto,
• a stand carriage movable along the vertical column, and
• a counter bearing for placing the object;
• a runner fastened to the stand carriage and displaceable relative thereto in a guided manner, the runner having
• an indenter to penetrate the object,
• at least one force generation actuator, and
• at least one motion generation actuator,
• wherein the indenter is coupled to the stand carriage via the actuators, and wherein the indenter, the at least one force generation actuator, the stand carriage, the base plate, the vertical column, the counter bearing, and the object define a force measuring circuit;
• a metrology frame that rests on the base plate and is supported laterally on the vertical column;
• and
• a displacement measuring unit for measuring a displacement of the stand carriage or of the runner,
• wherein the metrology frame, the displacement measuring unit, the runner, the indenter, the object, and the counter bearing define a displacement measuring circuit, and
• wherein the force measuring circuit and the displacement measuring circuit are configured separately from one another.
