1. General Description The metal Brinell hardness test uses a cemented carbide ball of a certain diameter and presses it into the surface of the material to be tested with a specified test force (Figure 1a) and after the specified holding time, remove the test force, (Figure 1b) to measure the indentation on the sample surface Diameter, to calculate the Brinell hardness, and calculate it with the following formula: )...

3.3 Panel diagram Button function instruction: 【Save】:Save current test data and save the test data in the historical data. 【Historical data】:View the historical data saved in the past, can be searched up and down, and delete the historical data, print or export the U disk. 【Clear】:It is used to clear the deviation of the initial force value caused by the long continuous operation of the sensor.
3.4 Time display area Display year, month, day and time display, long press the time display area can pop up the time to modify the numeric keypad, can be modified. Measurement input area: Enter the measured indentation diameter into the input box behind D1 and D2 to directly display the measured hardness value.
Click the circle in front of the ruler to be converted to select Dwelling time setting area: Click , it will pop up the numeric keypad and enter the number to set the dwelling time. ★ Note: When the test force error of the hardness tester exceeds the national standard, it shall be calibrated by the manufacturer or technical supervision department, and other personnel shall not enter the calibration test force menu.
●This machine is controlled by a microcomputer. If garbled characters or crashes occur, the machine can be restored to the working status by restarting the power. ●If you find other faults, please contact the manufacturer or supplier. Maintenance and Precautions ●The moving parts of the machine should be lubricated regularly (twice a month).
