Least Count of Vernier Caliper in
British System:
A vernier
calipers is a precision measuring (direct) instrument. Vernier caliper is made
of Nickel Chromium Steel.
The least count of vernier calipers is 0.001”
Calculations:
|
Least Count = 1 M.S.D. - 1 V.S.D. |
1 Main Scale
Division = 1/40"
=
0.025"
25 Division
of Vernier Scale = 24 Division of Main Scale
=24×0.025"
1 Division of
Vernier Scale = ( 24 x 0.025 ) /25
=0.024”
Least Count = 1 MSD - 1 VSD
=0.025"-0.024"
=0.001"
