Notes on the calibration of hardness testers
Before calibrating the HR-150 Rockwell hardness tester, do not use a hardness block to measure the reading error of the hardness tester. First, determine whether the working state of the verified hardness tester is in normal working state. This requires attention to the following issues

Discussion on troubleshooting methods for hardness tester faults
There are many types of hardness testers, and the commonly used ones in industrial and mining enterprises and research institutions are mainly metal Rockwell, Brinell, Vickers, and microhardness testers. Among them, metal Rockwell and Brinell hardness testers have a simpler structure compared to metal Vickers hardness testers. The repair of common faults is not very difficult. Below is an introduction to common troubleshooting of metal Vickers hardness testers.

Introduction to Vickers hardness tester
The Vickers hardness tester was first proposed by British scientist Vickers. Under a load of 49.03~980.7N, a square conical diamond with a relative angle of 136 ° is pressed into the surface of the material

Advantages of Vickers hardness tester testing
The Vickers hardness tester is used for measuring the Vickers hardness value of thinner materials. Using a rhombic diamond indenter, press it into the surface of the specimen under the action of experimental force, maintain it for a specified time, remove the experimental force, and measure the diagonal length of the indentation on the surface of the specimen.

How to troubleshoot common faults in Vickers hardness testers?
According to the Vickers hardness tester report, check the hardness tester switch, light bulb, etc. If these factors are ruled out and still do not light up, or if the loading indicator light or measuring microscope light does not light up, the repair method is to first check whether the power supply is properly connected.
