The parts of vernier caliper or Micrometer screw gauge is not important .
Important stuff is
How to take the readings from vernier caliper.
The first thing is to find the Least count of the Instruments
Formula is Least Count = Minimum division on main scale
---------------------------------------------------
Total No. of division on vernier scale/rotating scale
This formula is applicable for both vernier caliper and the screw gauge
To take down the readings use the formula
Total Readings of the object = Main scale reading + (Vernier scale reading x Least Count)
MSR + (VSR x LC )
The Lest count for Vernier caliper is 0.1mm or 0.01cm
Screw gauge is 0.01mm or 0.001cm
