Software functions:
System linkage: Through serial communication of the hardness tester, the system is linked with the hardness tester.
Pressure linkage: When the hardness tester test force is converted, the system senses the change in test force and displays it in real-time in the system.
Rotary tower linkage: The software controls the hardness tester to switch between the objective lens and the indenter, without the need for manual control of the hardness tester.
Loading linkage: The software controls the hardness tester to load, without the need for manual control of the hardness tester.
Measurement linkage: Software controls the turret of the hardness tester, loads and directly reads the Vickers hardness value.
Optical linkage: automatic focusing.
Image acquisition: Real time display of hardness images, capable of storing and printing images.
Automatic measurement: Automatically identify the four vertices of the indentation, fast speed, accurate data, and multiple professional algorithms to apply to different indentations. Continuous testing, instant testing, and specified coordinate compression.
Automatic point finding: Take points near the four vertices of the indentation, and the system automatically finds the best vertex, greatly reducing human error.
Diagonal measurement: Point at the upper left and lower right corners of the indentation to read the hardness value.
Four point measurement: Take the four vertices of the indentation and read the hardness value.
Hardness conversion: According to national standards, various hardness values such as Brinell Rockwell Vickers Knoop are automatically converted and displayed in real-time.
