Question

When the screw and stud touch each other, the edges of a certain screw gauge is on left of the  mark on the main scale and the 96th  division of the circular scale coincides with the circular line  graduation then what is the value of zero error

  1. zero errorequals plus 0.96 mm
  2. zero errorequals negative 0.96 mm
  3. zero errorequals plus 0.04 mm
  4. zero error equals negative 0.04 mm

The correct answer is: zero error equals negative 0.04 mm
