使用硬度計的注意事項 1、在(zai)更換(huan)壓頭(tou)或砧座時，注(zhu)意接觸部位要(yao)(yao)擦干凈。換(huan)好后，要(yao)(yao)用(yong)(yong)一定(ding)(ding)硬(ying)度(du)(du)(du)的(de)(de)鋼樣測試(shi)幾次，直到(dao)連(lian)續(xu)兩(liang)次所得硬(ying)度(du)(du)(du)值(zhi)相同為止。目的(de)(de)是(shi)使壓頭(tou)或砧座與試(shi)驗(yan)機接觸部分壓緊，接觸良好，以免影響試(shi)驗(yan)結(jie)果的(de)(de)準(zhun)確性(xing)。2、對(dui)形(xing)狀復雜的(de)(de)試(shi)件要(yao)(yao)采用(yong)(yong)相應形(xing)狀的(de)(de)墊塊(kuai)，固定(ding)(ding)后方(fang)可測試(shi)。對(dui)圓(yuan)試(shi)件一般要(yao)(yao)放在(zai)V形(xing)槽中測試(shi)。3、硬(ying)度(du)(du)(du)計本身會(hui)產生兩(liang)種誤差：一是(shi)其(qi)零(ling)件的(de)(de)變形(xing)、移(yi)動造(zao)(zao)成的(de)(de)誤差；二是(shi)硬(ying)度(du)(du)(du)參數(shu)超出規(gui)定(ding)(ding)標(biao)(biao)準(zhun)所造(zao)(zao)成的(de)(de)誤差。對(dui)第(di)二種誤差，在(zai)測量前(qian)需用(yong)(yong)標(biao)(biao)準(zhun)塊(kuai)對(dui)硬(ying)度(du)(du)(du)計進行(xing)校準(zhun)。對(dui)洛(luo)氏(shi)硬(ying)度(du)(du)(du)計校正結(jie)果，差值(zhi)在(zai)±1之...
