HYHV300T3.1 Microscope / Vickers Hardness Image Automatic Measurement System Function Introduction

1 Main functions: (There may be slight differences in different software versions)

• System linkage: The system uses RS232 interface to achieve system linkage with the hardness tester. The software controls the hardness tester in real time, adjusts the brightness, controls the turret, switches lenses, and loads the load and reads directly;
• Pressure linkage: After the hardness tester pressure conversion, the system senses the pressure change and adjusts accordingly;
• Turret linkage: The software controls the hardness tester to switch between the objective lens 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 and loading, and directly measures the hardness value;
• Platform linkage: Professional automatic platform and control, completely controlled by the system;
• Platform dragging: Drag the mouse on the active image to control the displacement of the platform in various directions;
• Focus linkage: T3.1 fully automatic system configuration. The computer controls the automatic rise and fall of the hardness tester leadscrew and automatic focusing. Manual raising and lowering of the leadscrew and observation for focusing is unnecessary. This saves time and effort, reduces human error, and improves accuracy;
• 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 indentation testing   Path planning. The edge normal can be set, Z Character, sawtooth, arc, and straight-line test paths;
• Path adjustment: Arbitrary adjustments such as adding, deleting, modifying, and moving can be made at path points;
• Measurement range: Supports from 10 grams to 50 kilograms of force;
• Image acquisition: Displays hardness image in real time. Images can be stored and printed, and the output magnification can be set;
• Automatic measurement: Automatically finds the four vertices of the indentation and directly reads the hardness value. It is fast and accurate;
• Diagonal measurement: Measurement is performed by tangential to the four vertices of the indentation with four lines, and the hardness value is read;
• Four-point measurement: The mouse clicks the four vertices of the indentation to read the hardness value, with simultaneous real-time display of the enlarged image;

• Automatic scanning: It can automatically scan the sample edge and contour;
• Hardness conversion: According to national standards, automatic conversion of Brinell - Rockwell - Vickers - Knoop and other hardness values is performed and displayed in real time;
• Depth curve: Plot hardness based on measured data - depth curve, can output dual hardness curve graph ( HV and HRC/HRA etc.).
• Graphic report: Automatically records measurement data and automatically generates hardness - depth curve, saves or prints hardness - depth curve, indentation image and all indentation measurements. All reports are in WORD document format;
• Image printing: Users can set the export mode of indentation images, which is divided into all images, current images or no images output;
• Results Statistics: The measurement results of multiple indentations are exported in EXCEL data format, and automatically statistics the number of measurements, maximum hardness, minimum value, average value, standard deviation, etc.
