Hey, folks! Today, let's talk about Mikrosize's star product, the MVicky - 1000T Touch Screen Micro Vickers Hardness Tester, a trusted companion for material research and quality control!
Before use, first inspect the instrument's appearance and connections to ensure the power supply is normal and the display screen is free of issues. Then, calibrate it with a standard hardness block according to the manual. Also, choose a quiet operating environment with appropriate temperature and humidity. When preparing samples, ensure their surfaces are smooth and clean, with a thickness at least 10 times the length of the indentation diagonal. For irregularly shaped samples, use suitable fixtures to secure them.
Next, set the test force and holding time on the touchscreen. Higher hardness materials require larger test forces, with holding times typically ranging from 10 to 30 seconds—confirm the settings after selection. Place the sample on the test stand, aligning it with the center of the indenter. Use the touchscreen to move the test head close to the sample, then adjust the focus through the eyepiece to clearly view the sample surface. Click "Start Test," and the tester will apply the set force, hold it for the specified time, and automatically unload. Avoid touching the instrument or sample during this process.
Once the test ends, the screen will display measurement data such as indentation diagonal lengths. If the device has an automatic calculation function, you can directly obtain the Vickers hardness value; otherwise, manually measure the two diagonals of the indentation with the included measuring microscope or tools and calculate the hardness using the Vickers formula. When testing multiple points, repeat the steps at different sample locations and record details like hardness values, test forces, and holding times for future analysis.
After testing, remove the sample, clean the indenter and test stand with a soft cloth, and tidy up the surrounding area. For long - term storage, keep the tester in a dry, clean place and perform regular calibrations and maintenance to ensure the Hardness Tster consistently delivers accurate results. Follow these steps, and you’ll master this robust tool with ease!
