花(hua)崗石使(shi)用方法：擰緊(jin)偏心軸把(ba)(ba)，首先要把(ba)(ba)固(gu)定(ding)(ding)座在儀座上固(gu)定(ding)(ding)好(hao)，然(ran)后按(an)被(bei)測(ce)零(ling)件長度(du)將活(huo)(huo)動(dong)座放(fang)置(zhi)在合(he)適的(de)(de)位置(zhi)上固(gu)定(ding)(ding)好(hao)。壓下(xia)球(qiu)頭手(shou)柄，裝入零(ling)件，用兩(liang)叮囑零(ling)件孔(kong)。擰緊(jin)固(gu)定(ding)(ding)手(shou)把(ba)(ba)，把(ba)(ba)固(gu)定(ding)(ding)好(hao)。然(ran)后把(ba)(ba)活(huo)(huo)動(dong)表(biao)座放(fang)在所需的(de)(de)位置(zhi)，配合(he)百分表(biao)或千分表(biao)方可進行(xing)檢測(ce)工作。
