เครื่องทดสอบความแข็งโลหะ Hardness Tester Brinell ITK-BMS-3000-OBLC

Usage of the Hardness Tester

Before turning on the hardness tester, make sure that the back of the hardness tester is inserted in the U disk，If there is no u disk，hardness measurement cannot save the measurement data very well. After connecting to power, the program will first initialize the U disk. After 3 seconds appears the main interface， the instrument is set up at the factory，to reset, please refer to the panel operation. If you test the Brinell hardness of 1000kgf force, install the 10mm ball indenter according to the display or instruction manual, Push the indenter into the spindle hole, close the bearing surface, and press the notch flat face against the ram (7 ), Slightly tighten the thumbscrew (7). the standard test pieces or test pieces on the test table (5), should be slowly and slightly rise the test table, until the specimen surface from the indenter about 0.5mm distance, press the "indentation" key, the indenter automatically fall, At this point loading, unloading test force (motor start), test force loading, unloading finished, the objective lens (14) to the front position, the screen back to the main interface.

Note: when the motor is working, it must not be moved to the test piece, must before moving please wait for the end of the loading and unloading, otherwise it will damage the instrument. Indentation can be seen in the micrometer eyepiece (9) field of view, then you can measure the indentation diagonal’s length in the micrometer eyepiece (9).If the indentation is not clear, you can slowly turn the rotary wheel, move up and down the test sets (5) till the image of the Indentation is the clearest. If two graduated lines seem vague in the Eyepiece, adjust the Eye Guard (10) till the graduated lines are the clearest, this is according to personal vision. Rotate the Right Drum Wheel (17) to move the graduated line of eyepiece, enable two graduated lines to be close. When inner side of two graduated lines are closely without limit (the inner side of graduated lines reach critical state with no space between them to allow the light penetrate, but two graduated lines are prohibited to overlap each other), press “Reset”, at this time, the d1: 0000 value on the main screen is zero (FIG.8), at the zero position for technique term. Now the length of diagonal line of indentation can be measured in the Eyepiece.
