Question

the screw and stud touch each other, the edge of a certain screw gauge is to the right of the  C mark on the main scale and 5th division of the circular scale coincides with the line of graduation then what is the value of zero error ?

  1. zero errorequals plus 0.95 mm
  2. zero errorequals plus 0.05 mm
  3. zero errorequals negative 0.05 mm

The correct answer is: zero errorequals plus 0.05 mm
