0:00 - Introduction
An introduction to the screw gauge , why we need a screw gauge and its usefulness.
0:22 - Construction
Vernier caliper consists of two jaws, one fixed and the other moveable , it also has two scales, namely the main scale and the vernier scale.
1:15 - Least count
The least count can be measured by deviding the pitch of screw with the total divisions on the circular scale. The least count of a typical screw gauge is usually 0.01 cm.
3:12 - Taking measurements
