Page 4: Unpacking Of Equipment
3 Unpacking Of Equipment Unscrew fixing steel sheet plates of upper side to wooden base of case and hold up upper side of wooden case by means of carrying handles. Take out two M8 bolts fastening equipment to lower wooden case. Locate equipment on a special table (see drawing of table enclosed) and fasten two M8 bolts by means of eye bull putting on flat testing table. -

Page 6: Brinell Hardness Testing (En 6506-1, Astm E10)
For Rockwell tests, HRC, HRA, HRD tests Rockwell Diamond indenter to be chosen while 1/16” ball indenter for HRB, HRF, HRG tests (see enclosed table) Using 1/8”, 1/4” ball indenters (optional) others tests can be also achieved. For Brinell tests, 2, 5 mm ball indenter to be used. Without using optical microscope, it is possible to see Brinell values directly on screen (depth measurement) please see Operational Manual of DIGIROCK for test menu enclosed. -

Page 19: Calibration
21 Calibration Important Notice: During calibration, 2 point calibration system used. Therefore, for each calibration, uppest and lowest test blocks must be choosen according to test meothods. For example, for HRC method, uppest block value 62-65 HRC, lowest block value 22-25 HRC arasında can be choosen. Your equipment is calibrated under related EN norms. - Page 20 You can add correction values for Brinell methods To save the calibration values as the factory settings registration password should be requested from our company. NOTE: If you done a wrong calibrations as the factory the calibration must be repeated.
