How To Use A Caliper

When it comes to getting your measurements right, no other tool will help you better than a Caliper. Because there is nothing to guess, there can be no misunderstanding, and there is absolutely no way of getting it wrong. So Here Is How To Use It:

  • The Vernier caliper is an extremely precise measuring instrument; the reading error is 1/20 mm = 0.05 mm.
  • Close the jaws lightly on the object to be measured.
  • If you are measuring something with a round cross section, make sure that the axis of the object is perpendicular to the caliper. This is necessary to ensure that you are measuring the full diameter and not merely a chord.
  • Ignore the top scale, which is calibrated in inches.
  • Use the bottom scale, which is in metric units.
  • Notice that there is a fixed scale and a sliding scale.
  • The boldface numbers on the fixed scale are centimeters.
  • The tick marks on the fixed scale between the boldface numbers are millimeters.
  • There are ten tick marks on the sliding scale. The left-most tick mark on the sliding scale will let you read from the fixed scale the number of whole millimeters that the jaws are opened.
