The daily inspection of a hardness tester with hardness test blocks is essential for precise measurement results. Using the QpixControl2 software significantly simplifies this process. The QpixControl2 software guides users through the daily check, saves data automatically and is easy to use. With the QpixControl2 operating software, the user can carry out daily checks efficiently and without extensive prior knowledge and ensure that all future measurements are based on correct values. Thus, a combination of hardness test blocks with the associated calibration project in the QpixControl2 software leads to accurate and reliable hardness measurements on a daily basis
