GBT4340.1，GBT4340.2，ASTM_E92

Test force application method

Automatic (loading, holding, unloading)

XYZ sample stage and movement control

The system provides XY electric moving sample stage and Z-axis control:

1. XY stroke: 50mm * 50mm Table size: 200mmX180mm, displacement repeatability<2um; XYZ displacement resolution can reach 2um;

2. XYZ movement speed can be adjusted

3. You can click the mouse to control the movement, or move or lift by inputting the movement distance, etc

4. The XY and Z movements can be controlled with a joystick, and the position can be fed back in a timely manner.

Loading mode and path settings

Multiple methods ensure that users can still obtain satisfactory measurement results even when the sample placement is not vertical or horizontal.

Two point method: Click on any two points on the sample image to specify the direction of movement of the stage;

Normal method: Select the normal tangent to the edge of the specimen as the direction of movement for the stage;

Angle bisector: By selecting the angle, the direction of the bisector is used as the direction of sample movement;

Arbitrary point method: Move the platform to any position, add loading points, and then load and measure at once.

Random point loading: Double click at any position on the platform, and the platform will automatically move the point to the center of the indenter field of view for loading and measurement.

Path adjustment: For the selected path, various operations such as horizontal mirror orientation, vertical mirror orientation, 90 degree, 180 degree, arbitrary angle rotation, and position translation can be performed.

fully automatic measurement

Automatically load point by point according to the set loading path, automatically focus, and automatically measure indentation to calculate hardness values, and draw a hardening curve;

Camera and calibration management

1.3 million pixel USB 2.0 CMOS dedicated for microscope measurement cameras

2. The camera can be calibrated using either a hardness calibration block or a calibration ruler

3. In order to improve measurement accuracy, different test forces can be calibrated separately and the system will automatically load them

Hardness value conversion and correction

Hardness conversion: The measured Vickers hardness value can be converted to other hardness values such as HB, HR, etc. in American, Chinese, or German standards;

data statistics

Automatically calculate statistical values such as the average and variance of hardness

Measurement algorithm

1. Superior automatic reading technology - Superior automatic reading technology can not only obtain sub-pixel, high-precision, and high repeatability results, but also is suitable for general indentation images, including images with small amounts of rust, scratches, uneven lighting, and shallow corrosion, with extremely fast measurement speed;

2. Unique manual point taking and automatic point finding technology - Users can roughly point near the four vertices of the indentation, and the system automatically identifies the best vertex position and reads directly; Satisfying the habits of ordinary users while greatly reducing their labor intensity;

3. General manual measurement methods - including 4-point measurement, 2-diagonal measurement, etc. When measuring 4 vertices, 4 vertices can be selected in any order for the convenience of users.

Hardening curve

Automatically draw hardening curve:

data storage

The original measurement data and images can be saved in the document for later calling out and printing the report; One file stores all the data of one measurement

Test Report

Automatically generate WORD or EXCEL document reports; The report format can be customized; The standard format includes hardness values, statistical values, indentation images, and hardening curves for each individual measurement point
