A caliper is a piano that can measure length much more accurately than a metric guide. The smallest step of the caliper you use is usually (1/50) mm = 0.02 mm = 0.002 cm. So the uncertainty in âˆ†x is (1/2) 0.002 cm = 0.001 cm.

__Valier caliper. A device used to measure small lengths, and this may be a distance similar to the diameter of the last cylinder or sphere, is called a caliper. With a vernier we can calculate calipers with an accuracy of 1/1000 __^{th} of a centimeter or even up to 0.1 mm

__Construction__: The caliper is made of a rectangular steel rod with cross section graduations in centimeters. This size is also called “Main (MS Scale)”. There is also a secondary dimension, consisting of tens that slide along the main scale. This scale is known as the Vernier scale (V.S). It has two sets of jaws that allow you to process the insideLower and outer diameters in combination with cylindrical objects.

__How it works__. To measure the length of an object, it is always placed between the two jaws of most calipers. The distance between the zero point of the main machine and the zero point of the vernier is equal to the length object. First we find the indication of the main scale, then the number of the vernier crossing one of the main scales. We multiply vernier units by a smaller number, and this happens when the reading of the main scale reaches the required length. To ensure the correct measurement, you need to get used to the zero error.

__Least Count or Constant:__ The vernier difference between the value of the scale’s major division and any vernier division becomes something called (VC) because of “Least Count (LC) or Vernier”.

## How many errors does a Vernier caliper have?

Zero errors are always detected in two types: Positive zero error. Negative error 0.

__Calculating the least amount__. Mathematically, the true value of the smallest continuous count or vernier is calculated as follows.

10 vernier scale = 9 main scale divisions = 9 mm

1 vernier division = vernier 9/10 mm

1 division = 0.main 9mm

1 step device= 1 mm

Lowest value = 1 – 0.9

Smallest number = 0.1mm__Least number = 0.01 cm__

The minimum number of stirrups can also be calculated as follows

L.C = value of minor division per MS / total number of divisions related to VS

CL = 1/10

CL=0.1mm__CL= 0.01 cm__

What happens as a result of incorrect graduations on caliper scales is often called zero error.

1.__No zero error:__ If the zero point of the main scale coincides with the zero point of the vernier, the instrument has no error.

2. Positive zero error: When the zero of the Venier scale refers to the right side of the zero of all major scales, the focus error is positive and the focus correction is negative. To get a positive zero error, look not at the vernier scale, but at the number of divisions of all the Venier scales that correspond to one of the higher divisions of the scale, and multiply this number by a smaller number.

3. Negative zero error: If the vernier zero is one of the valid zeros on the main scale, then the zero error will be negative Noah and zero correction will be successful. To find a zero error, look at the vernier league number multiplied by one of the main scales and compared with the fastest score.
