  • 1. Reading Micrometer and Vernier Calipers
  • 2. Micrometer
  • 3. Zero Error for Micrometer No zero error
  • 4. This micrometer has zero error.The zero marking on the thimble is below the datum line. So this micrometerhas a positive zero error.How do we count the zero error?In this case we will take the reading on the thimble.Thimble reading = 0.03 mmSo the micrometer has a zero error of +0.03 mm.Whatever reading we take on this micrometer we would have tosubtract +0.03 mm
  • 5. The zero marking on the thimble is above the datum line. So this micrometerhas a negative zero error.In this case we will have to count the number of divisions on the thimblebetween the zero marking and the datum line.No. of divisions = 3Measurement of each division = 0.01mmSo the micrometer has a zero error of -0.03 mm.Whatever reading we take on this micrometer we would have tosubtract -0.03 mm
