Micrometer head use:
1.micrometer head in the experiment is used to produce displacement and indicates that the displacement of the tool. General micrometer head before use, first turn differential cylinder to 10 mm place (in order to hold rod shaft forward after, the displacement of allowance), then micrometer head shaft sleeve on the main scale horizontal line to install your own to special support seat, mobile micrometer head installation set (micrometer head whole mobile) make rod and measured body connection and measured body in the appropriate position (depending on the specific experiment and decide) to tighten the support seat of fastening screw. When rotating micrometer head differential cylinder, measured body will with the rod and displacement.
3.Resolution is usually 0.01 , 0.005 mm, 0.002 mm and 0.001 mm, differential differential head up to 0.0002 mm
