HYHV300T2.1 Microscope / Vickers hardness image automatic measurement system function introduction

1 Main functions: (There are slight differences in different versions of software)

• System linkage: The system uses the RS232 interface to realize the linkage between the system and the hardness tester. The software controls the hardness tester in real time, adjusts the brightness, controls the turret, switches lenses, changes the load and reads the data directly;
• Pressure linkage: After the hardness tester pressure conversion, the system senses the pressure change and adjusts it in time;
• Turret linkage: The software controls the hardness tester to switch the objective - and indenter;
• Loading linkage: The software controls the hardness tester for loading without manual control of the hardness tester;
• Measurement linkage: The software controls the hardness tester turret, loading and directly measures the hardness value;
• Platform linkage ： Professional automatic platform and control, completely controlled by the system;
• Platform dragging: On the active image, drag the mouse to control the displacement of the platform in various directions;
• Direction setting ： According to the depth direction, set the corresponding platform displacement direction to ensure the best measurement results;
• Path planning: The automatic coordinate stage automatically moves the sample to the specified position according to the set trajectory; Multiple schemes support the planning of indentation test path, and the edge normal line, Z-shape, sawtooth shape, arc shape, straight line type and other test paths can be set;
• Path adjustment ： Any adjustments such as adding, deleting, modifying, and moving can be made at the path points;
• Measurement range Supports all force values from 10 grams to 50 kilograms;
• Image acquisition ： Displays the hardness image in real time. The image can be stored and printed, and the magnification of the output image can be set;
• Automatic measurement: Automatically finds the four vertices of the indentation and directly reads the hardness value, which is fast and accurate;

• Four-point measurement: The four vertices of the indentation are clicked by the mouse, and the hardness value is read. The enlarged image is displayed in real time;
• Automatic scanning: Can automatically scan the sample edges and contours;
• Hardness conversion: According to national standards, automatic conversion of Brinell - Rockwell - Vickers - Knoop and other hardness values are converted and displayed in real time;
• Depth curve: Draw the hardness according to the measurement data - depth curve, which can output a dual hardness curve ( HV and HRC/HRA etc.).
• Image report: Automatically records the measurement data, automatically generates the hardness - depth curve, saves or prints the hardness - depth curve, indentation image and all indentation measurement values. All reports are saved as WORD documents;
• Image printing: Users can set the export mode for indentation images, including all images, current image, or no image output;
