What are the Some tips to use Vernier Calipers?

As we all know by now, vernier calipers are most instrumental in taking measurements of linear dimensions. In order to take these measurements for the linear dimensions, while performing various important experiments in the Physics Laboratory, the vernier calipers equipment is unmatched in its efficacy. But the use of vernier calipers in the most accurate manner is most important so as not to get confused and wrongly apply them, ending up in recording wrong numbers. Vernier calipers not only used for linear measurements but also angular measurements.

When you are using the Vernier Calipers, the vernier caliper least count is important, as it can be used to calculate various other important quantities and measurements. Now in order to find the vernier caliper least count, the smallest number got on the vernier scale reading is divided by the total number of vernier scale division

Always calibrate the caliper before you start to use it, by closing the jaws and lining up the zero mark (0) on the scales. Now, place the object between the jaws and tighten them through sliding the moving scale. Do this until the jaws are against the object.

The recording of values on the main scale is done by moving the scale separately. You later add the values together and arrive at the final measurement.

So, the use of vernier calipers contains three stages:
First, you prepare the vernier caliper for action by locating the jaws in two sets.

Then, you read the scales that show inches or centimeters, beside divisions.

Now, ascertain the value of the smallest tick marks on the main scale.

Always remember to loosen the locking screw on the vernier calipers before you begin to use the scale.

Some tips to use vernier calipers
Always ensure the jaws are opened wide enough so that the object for measurement is properly fit inside for effective and accurate measurement

Always, read the line on the main scale that is aligning with 0 mark on the vernier scale

Now, check the first mark on the vernier scale that is lined up in alignment with the main scale

Now, it is easier to add the values
