Hi everyone! Today we are walking you through how to operate Mikrosize universal hardness tester step by step. This premium instrument is manufactured by Mikrosize, a professional supplier of precision testing and measuring equipment. Since 2009, Mikrosize has built a solid reputation in the industry for reliable inspection and measurement instruments, and this hardness tester stands out as one of its flagship products.
First, power on the MBRV-250A intelligent automatic universal hardness tester. It comes with an intuitive, user-friendly operation interface. Based on your test specimen material, rotate the test force adjustment handwheel to select the proper test force. This unit supports multiple hardness scales for different testing requirements. Use the directional keys to pick the matching scale: Option 1 is designed for non-ferrous metals, and Option 2 works for ferrous metals. Once selected, press the ENTER key. A conversion table will pop up on the main display; press ENTER again to confirm. The main screen will then show the activated scale for hardness scale conversion on universal hardness tester.
Next, use the directional buttons to open the DWELL menu and configure your hardness test dwell time setting. Navigate to the FUNCTION menu, select the first option Single (single test mode), then hit ENTER. Your MBRV-250A intelligent automatic universal hardness tester is now ready for automatic hardness testing for ferrous and non-ferrous metals.
Rotate the micrometer head, place your specimen firmly on the work stage, and adjust the micrometer to bring the sample close to the indenter. Watch the on-screen prompt once the indenter gently touches the specimen surface. Press the START button on the control panel. The hardness tester will automatically complete the full cycle: loading, dwell holding, and unloading. After the cycle finishes, the measured hardness value will appear clearly on the display.
Throughout the whole test procedure, make sure your specimen surface is flat and clean. This simple preparation is critical to getting accurate, repeatable hardness results.
The MBRV-250A intelligent automatic universal hardness tester delivers simple operation and reliable, high-precision material hardness inspection. Built with Mikrosize’s strict quality standards, it is a robust instrument for labs and production quality control. We hope this guide helps you master the workflow quickly and unlock the full performance of this hardness tester.
