What is meant by least count of vernier caliper?

What is meant by least count of vernier caliper?

Least count is defined as the smallest value a measuring device can measure and is also known as Vernier constant. Least count = Smallest reading on main scaleNumber of divisions on Vernier scale=1mm10 = This is the least count for Vernier Callipers. Hence, the least count for Vernier Callipers is 0.1mm.

How least count of vernier caliper is calculated?

The formula of Vernier calliper least counts is determined by dividing the smallest reading of the main scale with the total number of vernier scale divisions. The LC of vernier calliper is the difference between one smallest main scale reading and one smallest vernier scale reading of 0.1 mm 0r 0.01 cm.

Why the least count of vernier caliper is 0.01 mm explain?

When the two jaws of the instrument touch each other the 5thdivision of the vernier scale coincides with a main scale division and the zero of the vernier scale lies to the left of the zero of the main scale.

What is the LC of vernier calipers shown in Figure?

What is the LC of the Vernier calipers shown in the figure 7? Solution: One main scale division is 1 MSD = 1 mm. Since 5 VSD = 4 MSD, we get 1 VSD = (4/5) MSD = 0.8. Thus, the least count of this calipers is LC = MSD – VSD = 1 – 0.8 = 0.2 mm.

What is the formula of Vernier constant?

Vernier Constant, V.C. = 1 M.S.D.-1 V.S.D.

What is the maximum value range of vernier caliper?

The range (sometimes called maximum capacity) of a vernier caliper is the difference between the largest value and the smallest value that the caliper can measure. It is equal to the length of the main scale. Most vernier calipers have a range of 6 inches (300mm), although calipers with smaller and larger ranges are also available.

How to calculate accuracy of vernier caliper?

Part 2 of 2: Using the Caliper Slide one of the jaws against the object. The caliper has two types of jaws. Read the main scale where it lines up with the sliding scale’s zero. Read the Vernier scale. Find the first mark on the Vernier scale that lines up perfectly with any line on the main scale. Add the numbers together.

What is the least count of Vernier theodolite?

It is the smallest value that can be measured by a theodolite. V = d n . Where, v= Value of smallest division of vernier Scale . d= Value of the smallest division of main scale . n= no of small divisions on vernier scale. Least count of theodolites are generally 20″ and 15″ and so on.

What is the least count of Vernier and micrometer?

A Vernier scale on a caliper may have a least count of 0.1 mm while a micrometer may have a least count of 0.01 mm. The least count error occurs with both systematic and random errors. Instruments of higher precision can reduce the least count error.
