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 found by adding 3.00mm (left vernier caliper definition 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 vernier caliper pdf 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 (1732–1807) through his Traité d'astronomie (2 vols) (1764).[5] The name "vernier" was popularised by

One of these is fixed while the other is movable. 3. Outside jaws: They are http://verniercalipersguide.blogspot.com/ used for normal measurements of lengths of various objects. One of these is fixed while the other is movable. 4. Screw: It is used to fix the length between the jaws once the measurement of the object has been taken by the jaws. 5. Vernier Scale: It is similar to a normal scale but it has divisions which are different from the common 1 mm. 6. Depth Probe: It is a metal depth that is used for measuring depths, vernier caliper such as the depth of a cylinder. Least Count of Vernier Calipers Least Count refers to the smallest distance that can be measured using an instrument. It indicates the degree of precision of an instrument. Most of the vernier Calipers have a least count of 0.1mm. Least count can calculated using the formula. Least Count = Length of 1 MSD - Length of I VSD Where MSD and VSD refer to Main Scale Division and Vernier Scale Division respectively Generally positive zero error N divisions on main scale coincide with N-1 divisions on vernier scale 1 VSD is equivalent to (N-1)/N main scale divisions Using the formula for Least Count, we get LC = 1 MSD - 1VSD = 1 MSD - (N-1)/N MSD = 1/N MSD Example for Calculation of Least Count of Vernier Calipers: A vernier scale has the length of 9 main scale divisions and is divided in to 10 divisions. Calculate the Least Count of the Vernier Calipers. Solution: Since 9 divisions of the vernier scale coincide with 10 divisions of the main scale VSD = 9 / 10 mm = 0.9 mm MSD= 1 mm Least Count= 1 MSD- 1VSD = 1mm - 0.9mm = 0.1mm Formula for finding length using Vernier Calipers Length = MSR + (VSR * LC) Where MSR, VSR and LC refer to Main Scale Reading, Vernier Scale Reading and Least Count respectively. Zero Error Zero Errors quite often occur in measuring instruments due to defects in manufacturing. Vernier Calipers is said to have a Positive Zero Error is the zero of the Vernier Calipers does not coincide with the zero of the main scale when the two jaws are in contact with each other i.e. no object is held between the jaws. Appropriate correction is applied to get the correct length. Zero errors are of two types: Positive zero Error and Negative Zero Error. Positive Zero Error The Ve
