花崗石使(shi)用方法：擰(ning)緊(jin)偏心軸(zhou)把(ba)，首先要把(ba)固(gu)(gu)定(ding)(ding)座在(zai)(zai)儀(yi)座上固(gu)(gu)定(ding)(ding)好，然(ran)后(hou)按被測(ce)零(ling)件長度將活(huo)動(dong)座放(fang)置在(zai)(zai)合適的位置上固(gu)(gu)定(ding)(ding)好。壓下(xia)球頭手柄，裝入零(ling)件，用兩叮(ding)囑零(ling)件孔。擰(ning)緊(jin)固(gu)(gu)定(ding)(ding)手把(ba)，把(ba)固(gu)(gu)定(ding)(ding)好。然(ran)后(hou)把(ba)活(huo)動(dong)表座放(fang)在(zai)(zai)所需(xu)的位置，配合百分(fen)表或千分(fen)表方可進行(xing)檢測(ce)工作。
