scale. It is a scale that indicates where the measurement lies in between two of the marks on the main scale. Verniers are common on sextants used in vernier caliper reading navigation, scientific instruments used to conduct experiments, machinists' measuring tools (all sorts, but vernier caliper least count especially calipers and micrometers) used to work materials to fine tolerances, and on theodolites used in surveying. A close-up vernier caliper definition of a caliper's measurement scales. Assuming the caliper has no "zero error" (that is, it registers 0.00 mm when fully closed) the image shows a reading of 3.58mm ± 0.02mm. This is vernier caliper pdf found by adding 3.00mm (left red mark) read off from the fixed main (upper) scale to 0.58mm (right red mark) obtained from the sliding vernier (lower) scale. The main scale reading is determined by the rightmost tick on the main scale that is to the left of the zero tick on the vernier scale. The vernier reading is found by locating the closest aligned lines

between the two scales. The 0.02mm inscription indicates the caliper's precision and is just the width that corresponds to the smallest interval on the vernier scale.

Calipers without a vernier scale originated in ancient China as early as the Qin dynasty (9 AD).[1][2] The secondary scale, which contributed extra precision, was invented in 1631 by French mathematician Pierre Vernier (1580–1637). Its use was described in detail in English in Navigatio Britannica (1750) by mathematician and historian John Barrow.[3] While calipers are the most typical use of Vernier scales today, they were originally developed for angle-measuring instruments such as astronomical quadrants. In some languages, the Vernier scale is called a nonius. It was also commonly called a nonius in English until the end of the 18th century.[4] Nonius is the Latin name of the Portuguese as The name "vernier" was popularised by the French astronomer Jérôme Lalande (17

Zero Errors in http://vernierscaliper.com/vernier-caliper-working-calculation-of-least-count-zero-error-177.html Vernier Calipers and Micrometer Screw Gauge Nov 6, 2013 #1 kunkun Hi, I have a question to ask. On my notes that my teacher gave me, he said that there are some errors in the notes. He had not responded to me which are the errors yet but he said about zero errors in vernier vernier caliper calipers and micrometer screw gauge. The question is: On my notes, it says that: Vernier Calipers 1. Positive zero error occurs when the ‘0’ marking of the vernier scale appears after the ‘0’ marking of the main scale. The error is +x cm. To correct the reading, we subtract the error from the measurement. 2. Negative zero error occurs when the ‘0’ marking of the vernier scale appears before positive zero error the ‘0’ marking of the main scale. The error is -(0.1-y) cm. To correct the reading, we subtract the error from the measurement. Micrometer Screw Gauge 1. Positive zero error occurs when the ‘0’ marking of the thimble scale is below the horizontal reference line of the main scale. The error is +x mm. To correct the reading, we subtract the error from the measurement. 2. Negative zero error occurs when the ‘0’ marking of the thimble scale is below the horizontal reference line of the main scale. The error is -(0.1-y) mm. To correct the reading, we subtract the error from the measurement. The problem lies in the sentence: To correct the reading, we subtract/add the error from the measurement. About the subtracts in all the sentence, may I know which one should be add instead of subtract?

Vernier Caliper - Working, Calculation Of Least Count & Zero Error Vernier Caliper - Working, Calculation Of Least Count & Zero Error Posted on September 2, 2015 by Robert Thomson | 3 Comments Vernier Caliper: A device which is used to measure small lengths or distance such as diameter of a cylinder or sphere is called Vernier caliper. With the help of Vernier caliper we can calculate correctly up to 1/1000th of centimeter or 0.1mm Construction: A Vernier caliper consist of a rectangular steel bar whose one side is graduated in centimeters. This scale is also known as “Main Scale (M.S)”. There is also a small scale consisting of ten division which slides over the main scale. This scale is known as Vernier scale (V.S). It has two sets of jaws which enables it to measure the internal and external diameter of the cylindrical objects. Advertisement Working: To measure the length of an abject, it is placed between the two jaws of the Vernier calipers. The distance between the zero of the main scale and the zero of the Vernier scale is equal to length of object. First we find the reading of main scale then find the number of Vernier division which coincide with one of the main scale division. We multiply the vernier divisions by the least count and then ass to main scale reading to get the required length. To get the correct measurement we adjust for the zero error. Least Count Or Vernier Constant: The difference between the value of one main scale division and one vernier division is called as “Least count (L.C) or vernier constant (V.C)” Calculation Of Least Count: Mathematically, the value of least count or vernier constant is calculated as following. 10 vernier division = 9 main scale division =9mm 1 vernier division= 9/10mm 1 vernier division= 0.9mm 1 main scale division= 1mm Least count= 1-0.9 Least count= 0.1mm Least Count= 0.01cm The least count of vernier calipers can also be calculated as following L.C= Value of smaller division on MS/Total Number of division on VS L.C= 1/10 L.C= 0.1mm L.C= 0.01cm ###### Zero Error ##### The error which arises due to the incorrect gradation of the scales of the verneir calipers is called Zero Error. 1. No Zero Error: If the zero of main scale coincide with the zero of the Vernier scale then the instrument has no zero error. 2. Positive Zero Error: If the zero of the venier scale on the right of zero of the main scale then the zero error will be positive, but the zero correction will be negative. To find t
