The main scale contributes to the main number and one decimal place. Reading the caliper is a two-step process:
A Vernier caliper has two rulers: the main scale and the sliding Vernier scale. However, it can measure to the accuracy of one-thousandth of an inch (up to 2 decimal places). Reading the measurement on a Vernier caliper can be tricky. For example, if the main centimeter scale reads 0.85, and the Vernier 0.01 cm scale reads 12, adding them together results in 0.85 + 0.012 = 0.862 cm. The digits don’t always line up this neatly.In our example, we measured 2.6 inches on the main scale, and 0.014 inches on the Vernier scale.The only difference is the measurement reader. Vernier, dial and digital calipers consist of similar parts. The vernier scale allows much more precise readings to be taken (usually to the nearest 0.02mm or 0.001 inch) in comparison to a standard ruler (which only measures to the nearest 1mm or 0.25 inch). The main scale is graduated in either millimetres or tenths of an inch. Vernier calipers have both a fixed main scale and a moving vernier scale. Vernier calipers are super useful and a great tool to have in the tool box. However, it is also a very useful tool to use when measuring the diameter of a round objects like cylinders because the measuring jaws can be secured on either side of the circumference. In other words, it measures a straight line between two points. What is a Vernier Caliper?Ī vernier caliper is a measuring device used to precisely measure linear dimensions. Nevertheless, a digital caliper provides a wider range of measurements.
VERNIER CALIPER READING EXERCISES WITH ANSWERS MANUAL
On top of that, the digital variant needs a small battery while its manual counterpart does not require any power source. Vernier Calipers are operated manually and still available to be purchased and remain popular because of being cheaper in comparison to the digital variant.
As for the manual type of the tool – both imperial as well as metric scales are included. Dealing with a Vernier and interpreting its readings is rather difficult compared to using a Digital Caliper, its advanced version, which comes with an LCD digital display where all the readings are shown. The measured results are interpreted from the tool’s scale by the operator. The Vernier Caliper is a precision tool that can be used for measuring internal as well as external ranges/intervals with exceptionally high accuracy.
