This feature makes it possible to test and measure a wide range of materials with varying levels of hardness, ensuring that any specimen can be tested and measured within the applicable standards.
'N-Sure' Test and Measurement Software
The 'N-Sure' software programme is a highly versatile and efficient tool for automating the test and measurement process. With its flexible user interface, the programme offers increased productivity and operator efficiency by simplifying and streamlining testing procedures. The software can automate the test and measurement process as well as the optional motor-stage navigation process, ensuring that the application and removal of the test loads are performed fully automatically. This level of automation not only reduces testing time, but it also improves throughput and eliminates costly and time-consuming rework. Additionally, since the programme offers automatic preload, test start, and measurement capabilities, the repeatability of the testing process is excellent.
The software programme's automated preload application, main force application, indentation depth measurement, and hardness calculation are all performed automatically once the sample is clamped and the test cycle is initiated. In cases where the clamping nose is not used, the software will guide the operator to touch the indenter on the sample visually. Once the sample and indenter come into contact, the DUROLINE R will detect this and start the test cycle automatically. The programme eliminates the need for manual preload even with unclamped tests. If multiple measurements are required on the same or similar samples, the programme can recognise the previous contact position, thus eliminating the need to touch the indenter and sample again. The N-Sure software programme provides advanced database management of test results, report generation, and printing functions. In various industrial segments where testing the hardness results of critical components is a necessity, saving and retrieving measurement data is essential. The programme ensures that data is safely stored and presented in standard or customised reporting formats. With this software, generating test results and reports is both convenient and efficient.
