HB-3000 Brinell hardness is widely used in metallurgy, machinery manufacturing and scientific research institutes to do a variety of metal Brinell hardness determination. Through the daily verification of the instrument found the following common fault, now the repair method to do an introduction. First, the measurement of the correct use of reading microscope and adjustment In the Brinell hardness test, often found reading microscopes, micro-zero cylinder zero reticle and reticle zero
