What you need to know

  • Read the main scale first: it shows whole millimetres at the zero mark.
  • Work out what one small division is worth; on this caliper each vernier mark is 0.02 mm.
  • Find the vernier mark that lines up best with the main scale and add that value to the whole millimetres.
  • Practise with worked readings such as 5.72 mm and 16.2 mm, checking which side of halfway the pointer sits.
