Find the largest whole inch mark to the left side of this index line. So lets read a measurement off of the caliper. First a quick math refresher.

Whole numbers 123 etc are followed by a decimal point and an endless number of zeros 2000000. We are going to be working with the 3 places to the right of the decimal point. To do this you have to close the jaws of the caliper and note the value of the vernier scale which coincides with the main scale just like when reading the vernier scale.

This value should then be either added or subtracted from the total reading. How to Read A Vernier Caliper 1. Quantifying the Main ScaleThe first step of the measurement starts from the main scale.

From the video above the. Quantifying the Vernier ScaleThe second step is the vernier scale. The same with the main scale it provides.

Keep it the same and tighten the watch. Then hold the vernier and note the number directly below its vernier scale. After multiply the value of the Vernier scale by the point at which the Vernier scale and the principal scale coincide.

How to Read Vernier Calipers Inch Fractional and Decimal Readings This vernier caliper has two scales which enable read- ings to a fraction of an inch as in the case of 1128 graduated vernier upper scale or in decimals as in the case of 11000 graduated vernier lower scale. Each division on the fractional main scale represents. The Metric scale Reading the metric scale of the vernier caliper is a two-step process.

Read the main scale which gives you the number to the left of the decimal point Read the Vernier scale which gives you the numbers to the right of the decimal point. The Vernier caliper is an extremely precise measuring instrument. The reading error is 120 mm 005 mm.

Close the jaws lightlyon the object to be measured. If you are measuring something with a round cross section make sure that. Reading a Vernier A Vernier allows a precise reading of some value.

In the figure to the right the Vernier moves up and down to measure a position on the Scale. This could be part of a barometer which reads atmospheric pressure. Main at top vernier at bottom.

It reads 358 002 mm by adding 300 mm left red mark on the fixed main scale to vernier 058 mm right red mark. The main scale reading is that to the left of the zero on the vernier scale. The vernier reading is found by locating the best aligned lines between the two scales.
