Koopa Haresh Hardness Tester is used for capturing indentation image in Micro Hardness Tester in order to measure the indentation diameter and real hardness calculation in Brinell, Knoop, and Vickers methods. Each workpiece can be tested in 9 points and the results will be in one group. The hardness of each point is displayed and statistical calculations like maximum, minimum, average, range, and standard deviation are applied on the group. Method, Force, Magnification, and Indenter diameter can be selected by the software.

   The user can use two cursors in order to measure the indentation diameter in every direction. The user can have a color or black and white video or change the brightness as well. In Brinell and Vickers two diameters can be measured, but there is just one in Knoop method. The average diameter is used for hardness calculation in Brinell and Vickers methods. The average hardness is calculated whenever a new test is added to the group and this value is used for the average indentation depth.

   The optical system can be calibrated in two ways; direct calibration and indirect calibration. In direct calibration a micron/pixel coefficient has to be set to convert the distance in pixels into real distance. In indirect calibration a distance between two points has to be chosen on the image and then this distance has to be set in micron. The software automatically calculate the micron/pixel coefficient.
