It is a scale that indicates where the measurement lies in between two of the marks on the main scale.

used in surveying. A close-up of a caliper's measurement scales. Assuming the caliper has no "zero error" (that is, it registers 0.00 mm vernier caliper reading exercises with answers when fully closed) the image shows a reading of 3.58mm ± 0.02mm. This is 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 https://www.miniphysics.com/practice-on-reading-a-vernier-caliper-with-zero-error.html (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 astronomer and mathematician Pedro Nunes (1502–1578), who in 1542 invented a different system for taking fine angular measurements. Nunes' nonius was not widely adopted, being difficult to make and also difficult to read. Tycho Brahe used it on at least one instrument.[4][5][6] The name "vernier" was popularised by the French astronomer Jérôme Lalande (1732–1807) through his Traité d'astronomie (2 vols) (1764).[7] Construction[edit] In the following, N is the number of divisions the maker wishes to show at a finer level of measure.

Negative zero error in vernier calipers Jul 10, 2015 #1 quietrain https://au.answers.yahoo.com/question/index?qid=20070703200040AAU0ORD 1. The problem statement, all variables and given/known data Hi, with regards to the negative zero error , do we read the vernier scale from the left or from the right? In this case, vernier caliper should it be -0.04cm or -0.06cm? Thank you ! quietrain, Jul 10, 2015 Phys.org - latest science and technology news stories on Phys.org •Game over?

That is vernier caliper reading when it is slid to the right along the main scale. Look at A. You will see that first the 0.01 mark will align then the 0.02 one ... if the vernier is slit towards the right, as it is for normal measurements. But for C is is to the left of the zero on the main scale. That is is has slid a certain distance to the left of the 0 on the main scale. Now again look at A. The drawing is not completely correct in this case. The 0 on the right of the vernier should be aligned with the 9 mm mark on the main scale and the next vernier on the left should be slightly in front of the 8 mm mark, that is slightly to its right - maybe look at a real vernier scale if possible - the other vernier lines are more or less in their correct positions with respect to the millimeer markings on the main scale. So if you slide the vernier to the left from this point on the first one that will come into alignment is the 0.09 line then the 0.08 one .... so for negative readings you will

Yes No Sorry, something has gone wrong. Trending Now Answers Relevance Rating Newest Oldest Best Answer: When there is no object in between the jaws of the calipers, the reading of the caliper must be zero. Otherwise there is error in the instrument. Instead of showing zero reading, the instruments gave +0.05 units and hence the error is considered to be +0.05. In your instrument it is less than zero. Therefore it is negative error. Note the division of auxiliary scale that coincides with a main scale division. (Total number of divisions in the vernier - the number of division that coincides with the main scale) multiplied by least count gives the length that is away to the left of zero of main scale. That is negative error. This length has to be added to the reading taken when measurement is taken. Example: The least count of t
