Vernier Caliper is a measuring device used to measure more preciously .Its least measuring value is 0.01 mm . It has two upper jaws . Two lower jaws . and a needle .
In the Vernier caliper : The upper jaws are used to measure any inner diameter of any pipe or hollow cylindrical object .
just set the Vernier caliper into the cylindrical object . Now take the main scale reading . Now check on which Vernier scale reading is coinciding . divide VSR by 100 and add it to MSR ( Main Scale reading ) and you will get the diameter of the cylindrical object .
For Example If your main scale reading is 2 cm and Your Vernier scale reading is coinciding on 5th line
Your actual Reading is 2 + 5/100 = 2 + 0.05 = 2.05 cm
