| Loading Mode and Path Settings | Multiple methods ensure users can still obtain satisfactory measurement results even when the sample placement is not vertical or horizontal. Two-point method: Click any two points on the sample image to specify the movement direction of the stage;
Normal method: Select the normal to the sample edge to determine the stage movement direction;
Angle bisector: Choose an angle, and use the direction of its bisector as the sample movement direction;
Arbitrary point method: Place the moving platform at any position, add a loading point, and then perform a single loading and measurement.
Arbitrary point loading: Double-click any position on the platform, and the platform will automatically move that point to the center of the indenter's field of view to load and measure.
Path adjustment: For the selected path, various operations can be performed, including horizontal mirror, vertical mirror, 90-degree rotation, 180-degree rotation, rotation at any angle, and position translation. |
| Automatic measurement | Automatically load point by point along the set loading path, automatically focus, and automatically measure indents to calculate hardness values, and plot the hardening curve; |
| Camera and Calibration | 1, 3MP USB CMOS Camera; 2, support calibration by hardness blocks and micrometers 3, In order to improve measurement accuracy, different test forces can be calibrated separately, and the system loads them automatically. |
| Hardness conversion and compensation | Conform ASTM E140 |
| Data Statistics | Automatically calculate average hardness, variance, etc. |
| Measurement Algorithm | 1. Leading automatic reading technology — The leading automatic reading technology not only provides sub-pixel, high-precision, and high-repeatability results, but is also suitable for general indentation images, including those with slight rust, scratches, uneven lighting, or mild corrosion, with an extremely fast measurement speed;
2. Unique manual point selection and automatic point-finding technology — Users can roughly select points near the four corners of the indentation, and the system automatically determines the best corner positions for direct reading; this meets the habits of general users while greatly reducing their workload;
3. General manual measurement methods — Including 4-corner measurement, 2-diagonal measurement, etc. For 4-corner measurement, the four corners can be selected in any order, making it convenient for users. |
| Hardening curve | Automatically plot hardening curve |
| Data Storage | Original measurement data and images can be saved in the document for later retrieval and report printing; one file saves all the data of one measurement. |

Main Features:
1, XYZ Sample Movement Control: The system supports XY motorized sample stage movement and Z-axis control; including manual control, motorized control (joystick control), and automatic control (software control). X-Y directions can move synchronously. Motorized control uses a three-dimensional joystick, designed based on ergonomic principles, simple and convenient, and operates at will.
2, Software Control and Loading Modes:
2.1, Positioning Movement Loading: The stage moves directly to the software-set position for loading.
2.2, Fixed-Point Movement Loading: Select any point on the sample, move it under the indenter, and load.
2.3, Directional Movement Loading: Use mouse clicks to control the stage to move in any of eight directions; movement step size can be set and load applied.
2.4, Arbitrary Position Loading: Drag the stage with the mouse to move in any direction, allowing the user to view the sample surface; a loading point can be set at any position.
3, Variable Speed Movement: When the platform moves, five speed levels are available.
4, Other Functions: Arbitrary origin setting, automatic reset, mechanical limits, and other professional functions to meet various requirements.
5, Fully Automatic Operation: The system automatically moves along a preset multi-point path, automatically rotates the turret, automatically loads, automatically focuses, and automatically measures, while automatically plotting the hardening curve.
6, Hardness Value Conversion, Correction, and Effective Verification: The system can convert measured micro Vickers hardness values into other hardness scales such as HB, HR, etc.; it can also effectively verify sample measurement values.
