Answer 1

Okay something's up.

Answer 2

In any case, that usually depends on the micrometer itself and the threadforms in its core.

Answer 3

there r two scales in ur screw gauge

Answer 4

one is linear scale and another is circular scale

Answer 5

both scale have 0

Answer 6

if u rotate ur circular scale around linear scale

Answer 7

if at last both zeros match
then it has no error

Answer 8

if both zero do not match then it has error

Answer 9

if at last both zeros match
then it has no error

Answer 10
