 CUPOL: Vernier Caliper A vernier caliper (or vernier) is a common tool used in laboratories and industries to accurately determine the fraction part of the least count division. The vernier is a convenient tool to use when measuring the length of an object, the outer diameter (OD) of a round or cylindrical object, the inner diameter (ID) of a pipe, and the depth of a hole. This vernier's main scale is calibrated in centimeters with the smallest division in millimeters. phoenix.phys.clemson.edu /labs/cupol/vernier/index.html   (524 words)

 JQR 131.02 Vernier Caliper, Feeler and Telescoping Gage Training The vernier caliper is a precision instrument that is made to measure in thousandths of an inch. The vernier scale is attached to a movable jaw that matches the fixed jaw and slides along the main scale bar. Vernier calipers are also available with dial indicators and even digital liquid crystal display (LCD) heads which do not require interpolation (direct reading) and some convert to metric at the touch of a button. www.uiitraining.com /b51a/100/13102vernier_caliper,etc.htm   (1050 words)

 VERNIER   (Site not responding. Last check: ) This means that the distance between the first mark on the vernier and the first space on the scale; the distance between the nest two marks will be equal to 2/10 of a space on the scale and son on. Consequently, if the zero point of the vernier is shifted to the right 1/10 of a space on the scale, the first mark on the vernier will be directly opposite the first mark on the scale. This means that the zero point of the vernier is 4/10 of the distance between the fifth and sixth marks on the scale. www.scottdesignsundials.com /html/vernier.html   (489 words)

 [No title] Vernier scales are found on a wide range of instruments. The vernier consists of 50 divisions, meaning that 0.1 cm is divided into 50 parts and the final least count is 0.1 cm/50 = 0.002 cm = 1/50 mm. A reading of 1.6 from the vernier really means 0.016 cm which is added to the main scale reading to give the final diameter of 3.216 cm. www.rit.edu /~uphysics/VernierCaliper/caliper.html   (953 words)

 Vernier scale   (Site not responding. Last check: ) In spite of years of experience, instrument makers have never found it possible to assemble the circle and verniers onto the instrument bearings with as geat accuracy as can be obtained in the engraving of the scales themselves. The mark on the vernier scale which most nearly coincides with a corresponding mark on the main scale represents the vernier reading (using the vernier scale numbers, of course). Since the scale is divided into half degrees and used with a vernier numbered from 0' to 30', it will be necessary to add 30 minutes to the vernier reading when the vernier scale index reads against the second half degree interval on the main scale. physics.usask.ca /~angie/ep421/lab1/vernier.htm   (279 words)

 Vernier scale Summary The vernier was ahead of its time for in the seventeenth century survey instruments were not precise enough to require the detail that the vernier could provide. Verniers are common on sextants, scientific instuments and machinists' measuring tools (all sorts, but especially calipers and micrometers) and on theodolites. Now if you move the vernier by a small amount say one tenth of its fixed main scale, the only pair of marks which come into alignment will be the first pair since these were the only ones originally misaligned by one tenth. www.bookrags.com /Vernier_scale   (974 words)

 Visual Acuity ↔ Hyperacuity The vernier and the Landolt C are redrawn with random directions. For me, at reading distance, vernier resolution is ≈0.05 pixel, while I cannot recognize the Landolt C below ≈0.5 pixel gap size (the absolute limit depends on the distance, on your eyes and your visual display unit). Vernier acuity is also called hyperacuity, because its resolution is 5-10× higher than that of visual acuity. www.michaelbach.de /ot/lum_hyperacuity/index.html   (490 words)

 vernier1 Two such instruments that are based on a vernier scale which you will use in the laboratory to measure lengths of objects are the vernier callipers and the micrometer screw gauge. The main scale reading is the first reading on the main scale immediately to the left of the zero of the vernier scale (3 mm), while the vernier scale reading is the mark on the vernier scale which exactly coincides with a mark on the main scale (0.7 mm). The vernier calipers found in the laboratory incorporates a main scale and a sliding vernier scale which allows readings to the nearest 0.02 mm. www.phy.uct.ac.za /courses/c1lab/vernier1.html   (1141 words)

 Vernier biography Being born in Franche-Comté (Free Country) meant that Vernier (and his father) were involved, not with the government of France but with that of Spain. Vernier became a government official holding various positions such as military engineer for the Hapsburgs and director general of the treasury in Dole and Besançon, the capital of Franche- Comté. It has two graduated scales, a main scale like a ruler and a second scale, the vernier, that slides parallel to the main scale and enables readings to be made to a fraction of a division on the main scale. www-history.mcs.st-and.ac.uk /history/Biographies/Vernier.html   (381 words)

 How to read a vernier scale--using verniers The vernier "0" is between 30.4 cm (304mm) and 30.5 cm (305mm). Likewise, for the inch vernier, to read to 0.001", one must have 50 graduations on the vernier over 49 spaces of 1/20" (or 0.05") graduations on the true (or main) scale (1/50 x 1/20 =.001"). "0" on the vernier is between 12.000" and 12.050" on the true scale. www.schlenkent.com /vernier.htm   (399 words)

 ISP Planet - Fixed Wireless - Business - Vernier Networks' Strange Convergence The chief technology officer of Vernier Networks expects that all computer users will be wireless, data networks will have borrowed a page from cell phone companies to run customer premise access nodes, and Vernier's technology will be the foundation of this new world order as a dominant security architecture. Vernier makes equipment designed to do just that, and investor optimism is rooted in the belief that today's average \$100,000 Vernier installation will, in the future, become a more ambitious \$1,000,000 installation. ARINC's story puts Vernier's ISP pitch in perspective—after all, ISPs running wireless POPs or extending their access portfolio with wireless access options would be expected to provide some degree of security and QoS, especially if business customers are a target audience. www.isp-planet.com /fixed_wireless/business/2003/vernier.html   (935 words)

 The Open Door Web Site : IB Physics : Measurements : The VERNIER Scale   (Site not responding. Last check: ) A Vernier scale is a small, moveable scale placed next to the main scale of a measuring instrument. Notice that 10 divisions of the Vernier scale have the same length as 9 divisions of the main scale. Hence, the level of precision of an instrument which has a Vernier scale depends on the difference between the size of the smallest division on the main scale and the size of the smallest division on the Vernier scale. www.saburchill.com /physics/chapters/0095.html   (450 words)

 Vernier Micrometers The fourth decimal place in ten-thousandths of an inch (0.0001") is obtained by reading the vernier lines on the sleeve. One of the lines on the thimble will align with one of the vernier lines on the upper portion of the sleeve. Reading the vernier portion involves some judgment on the part of the reader. regentsprep.org /Regents/math/tools/microm.htm   (227 words)

 Reading a Vernier The 0 line on the vernier lines up at 756 on the scale, but the 10 line on the vernier lines up at 765 on the scale. Thus the distance between the divisions on the vernier are 90% of the distance between the divisions on the scale.

 ScienceDaily: Infant Vernier Acuity Is Comparable To That Of Adults Vernier acuity is tested by viewing nearly collinear stripes with varying amounts of spatial phase displacement between them and measuring an individual's ability to gauge the displacement between the stripes. The vernier acuity of the infants and adults was then tested under the same conditions as the contrast discrimination had been tested. The similarity of infant and adult vernier acuity suggests that vernier acuity might be a sensitive test for strabismic amblyopia and other visual disorders that normally must be diagnosed using an eye chart. www.sciencedaily.com /releases/2005/05/050528145844.htm   (807 words)

 HOW TO USE THE VERNIER CALIPERS   (Site not responding. Last check: ) The vernier calipers are used to make accurate measurements of both “outside” and “inside” dimensions of objects by using both fixed scales and a vernier scale on a sliding piece. Look at the position of the vernier scale in relation to the fixed scale as seen in the window of the slide. The measurement will be the total of that part of the fixed scale to the left of the vernier scale plus that number of divisions of the vernier scale that are to the left of the position where the two scales most nearly line up. classroom.sdmesa.net /mcrivello/vernier.htm   (342 words)
