	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.

	Weighing scale - Patent 4836315
		The slit on the vernier scale that is filled in the background by a graduation on the beam is the pertinent unit value to be read.
		Generally, the graduations of the auxiliary vernier scale such as on calipers, for example, are at the edge of the vernier slider and run next to the stationary primary graduations on the non-sliding part of a caliper, for instance.
		The vernier scale may be made of a fl material and the stationary graduations 52 may be embossed or otherwise printed with white paint or the like so there is good contrast between the fl plastic separating the slit 54 and the graduation marks 52.

	Vernier Scale
		So the divisions on the vernier scale are not of a standard length (i.e., inches or centimeters), but the divisions on the main scale are always some standard length like millimeters or decimal inches.
		A vernier scale enables an unambiguous interpolation between the smallest divisions on the main scale.
		Since the vernier scale pictured above is constructed to have ten divisions in the space of nine on the main scale, any single division on the vernier scale is 0.1 divisions less than a division on the main scale.

		When the measurement is taken, the zero point of the indicating scale will lie at the true datum of the measurement.
		The number at the aligned gradation of the indicator scale will be the extra data of the measurement.
		Verniers are common on sextants, machinsts' measuring tools (all sorts), and slide rules.

		Thus the measured position is almost exactly 756 in whatever units the scale is calibrated in.
		Thus the distance between the divisions on the vernier are 90% of the distance between the divisions on the scale.
		If we do another reading with the vernier at a different position, the pointer, the line marked 0, may not line up exactly with one of the lines on the scale.

	XTant project - Build your own sextant
		In the vernier scale sextant, each degree in the scale is divided in 3 ticks (20' wide).
		In the vernier scale (the one from A to 20') we can see that the 6th vernier tick coincides with the arc scale tick (give it or take).
		The arm window (where the scale is read) must be sized and positioned so that you can see both the scale and the vernier touch point (that will define the arm radius).

	Grand Admiral Petry at NEMO: logarithmic vernier
		Verniers are found in various constructions, on micrometers including straight linear, rolling-linear with a geared dial running a linear track, screw-winding-linear where the control turns a high-precision screw to advance straight linear calipers...
		The vernier auxiliary scale was added to the reticule on linear rules to improve resolution of the finest graduation-- it relied on the mechanical stability, accuracy, and visibility of the rule to provide more than first-readable delineation of precision.
		As the finest graduations were nearly linear (whence linear-interpolation was taught) the application would have required matching the vernier scale to the two adjacent best-or nearest-coincidences, counting the graduations between -that being the proportion modulus- usually not convenient tenths: and varying locally, too.

		Vernier calipers use a special sliding scale enabling a linear measurement to be read more accurately.
		The Vernier, which was invented by a French mathematician of that name, who died in 1637, can be applied to all kinds of linearly divided scales including degrees and minutes.
		The accuracy of the readings depends on the marking of the vernier scale, which on the SM098 vernier calipers is capable of giving a reading with a precision of 0.02 mm on the centimetre scale and 0.001 inch on the inches scale.

		The other part is a slider with a “jaw”, viewing window (with vernier scale), adjusting roller, and a locking screw.
		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.

	Vernier scale - Wikipedia, the free encyclopedia
		Verniers are common on sextants, scientific instruments and machinists' measuring tools (all sorts, but especially calipers and micrometers) and on theodolites.
		The indicating scale is constructed so that when its zero point is coincident with the start of the data scale, its gradations are at a slightly smaller spacing than those on the data scale and so do not coincide with any on the data scale.
		N gradations of the indicating scale would cover N-1 gradations of the data scale (where N is the number of divisions the maker wishes to show at the finer level).

		Now we swing the upper scale to the left, always moving towards the larger angle, until the first mark to the right of zero on the vernier scale aligns with a mark on the upper scale (photo 2nd from left).
		Swing the upper scale again until the 3 on the vernier scale lines up with the 3 on the upper scale (4th photo from left).
		We then locate the 7 on the vernier scale and move the gauge towards the larger angle (towards 33 and not 32) stopping on the first mark that lines up with the 7 (right).

		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.

		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.

	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.

	Using the Vernier Scale (Site not responding. Last check: 2007-10-13)
		Instead of 10 (actually.10) on the Vernier scale being equal to 9 on the Standard scale, it is equal to 1.9 on the Standard scale.
		Since the stationary (Vernier) zero mark is between the fourth and the fifth division, the weight is between 4.4 and 4.5 grams.
		To use this Vernier scale, you look at the stationary (Vernier) scale marks to see which of them matches best with the corresponding Standard scale mark.

	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.

		A Vernier scale allows very accurate measurements to be made.
		One is the main scale, which is typically graduated to measure distance or angle.
		In addition, there is the reference against which the scale is measured; this consists of a marker which denotes a point on the main scale, and above this graduations from '1' to '0'.
