Question

What is the PSR of screw gauge

Answer 1

Answer:

linear scale reading

With the lead shot between between the screw and anvil, if the edge of the cap lies ahead of the Nth division of the linear scale. Then, linear scale reading (P.S.R.) = N. If nth division of circular scale lies over reference line.
