Innovative design of operation control keys and LCD display screen. Designed as a menu style structure, it can display indentation diagonals D1 and D2, hardness scale HV or HK, hardness value, test force, holding time, measurement frequency, Vickers Rockwell conversion value, date and time, measurement statistics, and loading process on different pages.

In the system settings menu, the test force unit (gf or N), LCD backlight, date, and time can be set separately. By touching the keys, the brightness of the light source can be infinitely adjusted, the tower can be rotated, and the loading can be controlled. The instrument also has a power-off memory function and a timing device for measuring positions. Through the printer, measurement data such as maximum value, minimum value, uniformity, mean value, and mean square error can be output.

Novel design of control buttons and LCD display. Auto motorized tureet.

With the touch buttons and the LCD screen, it is easy and visual to set hardness scale (HV or HK), date; to select the force unit (gf or N), force duration; to adjust the background of LCD and the brightness of illuminating lamp; to operate the turret; to display and output diagonal lengths D1-D2, measured HV or HK hardness values, statistics (Max, Min, Ave, deviation), converted HRC HRA values, and etc.
