Stainless Steel Pi Tape

32-300 (Stainless Steel) Make:- M.S.Technology L.C- 0.01mm Range- 32-300 mm, L.C-0.01 mm To Read (follow the steps) 1) Main scale has a least count 0.5 mm for Range (32-300 mm) 2) Wrap a pi tape around pipe, and check the zero line of vernier scale. 3) Suppose The zero on vernier is passed the 140 line on main scale. 4)Now find the line on vernier which corresponds (match) exactly with the main scale line. 5)Lets say 5th line is exactly matches to main scale reading then (5* 0.01 = 0.05 mm) this added to the 140 reading gives on outside diameter as 140.05 mm
