Embodiment takes 150r/min), close motor 2 after keeping X (22～24, take 22 in concrete the present embodiment) hour, take out all
Treating test sample block 14 and standard sample 14, and weigh respectively, then former state reinstalls the packaged chuck of sample 11；
B step by step: open motor 2, and make the rotating speed of main shaft 4 maintain mid ranger (250～350r/min, concrete this
Embodiment takes 250r/min), close motor 2 after keeping Y (46～48, take 46 in concrete the present embodiment) hour, take out all
Treating test sample block 14 and standard sample 14, and weigh respectively, then former state reinstalls the packaged chuck of sample 11；
C step by step: open motor 2, and make the rotating speed of main shaft 4 maintain top gear (400～500r/min, concrete this
Embodiment takes 400r/min), close motor 2 after keeping Z (70～72, take 70 in concrete the present embodiment) hour, take out all
Treat test sample block 14 and standard sample 14, and weigh respectively；
It is significant to note that, the present embodiment explicitly points out:
Step by step in a, after main shaft 4 maintains low or first gear to rotate 0.5X hour, close motor 2, by upper for packaged for sample chuck 11
Treat that test sample block 14 and standard sample 14 position are exchanged in same diameter line, be then turned on motor 2, make main shaft 4 maintain low or first gear
