- 1. Micrometer How to use Micrometer Dr. Mohd Aslam SITCOE Yadrav
- 2. Part Names
- 3. Basic steps in micrometer measurements Reference Line Main Scale Reading Circular scale or thimble reading Least count= (pitch / total no. of division) Pitch= gap in between anvil and spindle
- 4. How to Calculate Micrometer Reading Total length=MSR+CSR X L.C. MSR=Main Scale Reading CSR=Circular Scale Reading L.C.=Least Count
- 5. How to Calculate Corrected Reading Corrected Reading=Observed Reading±C Case 1: Positive Zero Error (+0.02 mm) e.g. Corrected Reading=6.74 0.02=5.22 −
