  • Dial Caliper vs. Metric Vernier Caliper

    Vernier, dial and digital calipers are all designed for accuracy up to 0.001 inch, or 1 thousandth, plus or minus 0.001 inch per 6 inches. They all make outside, inside and depth calculations. The vernier caliper was the first type produced. All of these calipers are useful for measuring anything that requires no more than a 0.003 inch of tolerance due to the plus or minus equation.

  • How to Compress the Rear Calipers on a 2004 Nissan Altima

    The 2000 Nissan Altima was equipped with a transverse mounted, 2.5-liter inline-four cylinder, or optional 3.5-liter V-6 engine. The Altima used front-wheel drive with either an automatic or manual transaxle. Front disc and rear drum brakes came standard, but rear disc brakes were available as an option. The parking brake on the Altima is incorporated into both rear calipers. A special procedure must be used to compress the piston.

  • How to Rebuild a Lucas Caliper

    Solid brakes are a critical safety component in any automobile. Modern disc brake systems employ a combination of master cylinders and wheel calipers. If your car pulls to one side when you apply the brakes or if you notice a loss of brake fluid, chances are that one of your wheel calipers is not functioning properly and should be rebuilt. Fortunately, once the caliper is out of the car, rebuilding it is fairly easy.

  • What Is a Swinging Caliper?

    Swinging calipers aren't quite rare enough to qualify as an automotive oddity -- BMW's been using them for years -- but they certainly do fall outside of the norm for most cars. The swinging caliper offers a number of advantages over traditional floating calipers, but lacks the compact versatility of its more straightforward siblings.

  • Types of Micrometer Calipers

    The micrometer caliper, also known as “mike,” is a measuring device used when exact measurements to within one ten-thousandth (0.0001) of an inch are needed with great accuracy. It is a high-precision measuring tool with a fine thread that is rotated to obtain measurements using a Vernier scale. It has two movable cylindrical pieces that move farther or nearer each other in the process of measurement.

  • How to Measure Miniature Bearings

    Miniature bearings allow rotation of a wheel on a rotating shaft fluidly without friction. Miniature bearings are used in remote control cars and trucks, skates of all types and skateboards. The balls inside the race of a bearing need lubrication to allow the wheel to spin correctly. Non-lubricated bearings do not allow the balls to spin and the wheel locks up. Measuring your faulty miniature bearings allow you to correctly obtain a replacement in the same size.

  • How to Read a Sextant Vernier

    Sextants are marine instruments used to calculate the angle between two objects. They're used for celestial navigation. John Bird created the first sextant in 1759. Since that time the instrument has been continually improved and is still used today. A vernier sextant has a second dial -- the vernier -- to measure smaller readings. This dial eliminates the need to estimate, resulting in more accurate measurements.

  • How to Count on a Meter Stick

    Each measurement tool has its own set of skills that you must master to use and to read. Most people already have the skills necessary to use a meter stick to measure things, as they are the same as that for a yardstick. To read the measurement on a meter stick, you must be familiar with the principles of the metric system. The meter stick measures length and does so in the units of meters. Based on the metric system of units, you can breakdown the units of measure into smaller gradations.

  • How to Remove a Dial Caliper Pointer

    Dial calipers are a common tool used by many professionals, such as engineers and mechanics. They come in many different sizes and can vary in cost. Calipers allow you to check both internal and external dimensions, are highly accurate and are easy to use. Repairing calipers is fairly easy and usually requires no specialized training or tools. Parts are readily available and inexpensive.

  • The Vernier Caliper for Mass, Volume & Density

    Vernier calipers are instruments used primarily in laboratory settings to measure specific distances, such as the outer diameter of a round object. Mass, volume and density are interrelated, as density is equal to mass divided by volume. In order to obtain the numbers for this equation, the Vernier caliper becomes a necessary tool in the laboratory.

  • How to Set a Dial Caliper to Zero

    Calipers allow precision measuring of various objects. In the metalworking industry, items such as screws, plates, thicknesses, depths and gaps need to be measured in increments smaller than millimeters. A pair of calipers allows consistent measurements for production of precision equipment. Industries such as metalworking, gun making, machining, woodworking and medicine use calipers to obtain very minute measurements. A dial caliper can measure outer, inner, depth and step dimensions. Cleaning or adjustments may be needed to have a properly working caliper. Setting a dial caliper to zero takes only a few moments and should be performed before taking any measurements.

  • How to Measure Gems With Calipers

    Jewelry design and manufacturing requires a knowledge of gem size. In order to measure gems, you will require a special tool called calipers. Calipers can be manual or digital but, in either case, the directions for usage are the same. You are able to measure both the outside and inside of a gem. The outside measurement will provide you with a length and width value while the inside measurement can give you the size of the center hole in the gem.

  • How to Read a Sliding Vernier Caliper

    A caliper can measure both outside and inside dimensions of objects, as well as the depths of holes. But like any instrument, a caliper is limited by its "instrument least count." The instrument least count is the maximum precision measurable by an instrument, as determined by the size of the spacing between its division marks. Tools that use an additional, auxiliary scale, called a vernier scale, can overcome this precision limit. The sliding vernier caliper can subdivide the instrument least count from 10 to 100 additional subdivisions further than a typical caliper.

  • How to Read a Vernier Caliper in Inches

    Scientists use Vernier calipers to measure many aspects of plant or animal specimens. These calipers can also measure the inside or the outside diameter of cylinders and thus have a variety of uses. Vernier calipers can take very precise measurements, with error readings of less than a tenth of a millimeter. These calipers have a sliding scales and must be read in two steps. Because many Vernier calipers are in a metric scale, simple multiplication can convert the reading into inches if necessary.

  • What Does a Negative Zero Reading on a Vernier Caliper Mean?

    Vernier calipers are used to measure items with great accuracy. Normal measurement units are in centimeters, down to the millimeter engraved along the long arm called the fixed main scale.

  • How to Use Micro Calipers

    Micro calipers allow you to measure the inside or outside diameter of an object with a degree of accuracy in the microscopic range. Micro calipers work by using a set of jaws and a microscopically graduated scale. One jaw remains stationary while the other moves toward or away from it. The action of moving the free jaw is most accurately accomplished using a dial or some other method that gives the user control over the movement. A thin wire, digital display, or a dial readout helps the user accurately take measurements.

  • How to Read a Digital Caliper

    Digital calipers are a form of vernier caliper that provide highly precise measurements. Unlike their manual cousins, the digital version of the caliper displays the exact value of the measurement, providing you with precise data assuming it's calibrated correctly. These instruments are commonly found in industrial or manufacturing settings, as well as school machine shops. If you are machining parts to a certain precise specification, it's very likely you'll need to use a digital caliper at some point during the process.

  • The Advantages of Using a Vernier Caliper Instead of a Meter Stick

    Although you can use either for measuring lengths in metric units, a vernier caliper has greater precision than a meter stick. You can use a meter stick for quick measurements of objects ranging from about 5 to 95cm. Technicians and craftspeople use vernier calipers to precisely gauge objects typically smaller than 16cm, or about 6 inches.

  • How to Attach the Brake Assembly for Huffy Bikes

    If you've ever ridden a bike, then you know just how critically important the brakes can be. Without the brake assembly, you'll be at the mercy of your own inertia, and you could end up flat on your face or in a bad collision. Huffy bicycles typically come with the brake assembly halfway installed, but further adjustments must be made as you assemble the bicycle brake system. In order to install the assembly properly, you'll need a few basic tools.

  • How to Use a Caliper Tool

    The caliper is an indispensable tool for a number of craftsmen, hobbyists and metal workers. While they are not difficult to use, calipers take a meticulous eye and a patient hand in order to use them well. The caliper in wide use today is the vernier caliper, first created in 1851 by Joseph Brown. It was widely accessible because of its low cost and precise measurements. It is the foremost caliper used today, available at a far more affordable cost than when it was conceived.

  • How to Use a Non-Digital Caliper

    Calipers or micrometers are useful in measuring small diameters both inside and outside an object. Calipers record measurements in thousandths of a foot for technical information on blueprints, drawings, woodworking and measuring artifacts. There are two types of non-digital calipers: the Vernier manual calipers and dial-type calipers. Vernier manual calipers are the least expensive type and are available in a plastic version.

  • How to Use Hermaphrodite Calipers

    A caliper is used to obtain precise small measurements and is used in a wide variety of professions and crafts, such as drafting, woodworking, metalworking and gunsmithing. The oldest known caliper dates from the 6th century B.C. Types of traditional calipers include inside, outside, divider and hermaphrodite. Modern calipers include vernier, dial and digital. Hermaphrodite calipers are also known as odd leg or odd leg jenny and are used to scribe lines parallel to an edge.

  • How to Determine the Power in an Inductor

    In electrical design, inductors allow power from current flowing through a wire to be temporarily stored within a magnetic field. While the power an inductor can store grows exponentially as amperage increases, it also depends on the inductor coil's shape and other physical characteristics. The overall effect of these dimensional factors is known as the coil's "inductance."

  • Types of Calipers

    Calipers refer to a type of tool used to measure distance. The tool consists of two movable legs that are attached at one end. The legs of the calipers are placed inside or outside of an object and then moved together or apart so that the space between the legs of the caliper is equivalent to the thickness or diameter of the object. The distance between the legs is then measured with a ruler or other measuring device to determine the thickness or diameter of the object.

  • How to Replace Brake Pads on a Harley

    Disc brakes today on a Harley Davidson motorcycle require very little maintenance except for periodic fluid bleeding and replacement of the brake pads. Manufacturers have been producing many kinds of replacement brake pads and making various claims about their products. However, the manufacturer of your motorcycle may require that you purchase and use genuine factory parts. It's very important to replace parts according to the manufacturer, especially if your bike is still under warranty.

  • How to Use Calipers in Sculpture

    Creating a sculpture can be a complex activity. When sculpting a realistic representation of a person, having correct measurements and proportions is an important aspect to ensuring realistic results. There are many ways to measure proportions using calipers help to ensure that measurements are consistent.

  • How to Zero a Dial Caliper

    A dial caliper is a measuring instrument with an accuracy rivaling that of a micrometer. Both devices can measure to the nearest thousandth of an inch. The advantage of a caliper is that you can measure up to several inches in length with having a whole set of them as would be necessary with micrometers. The slightest bit of wear on the moving parts of the dial can throw off the accuracy of the zero setting. Fortunately, a provision is made so that you can easily adjust the zero on your dial caliper.

  • Reading Caliper Dials

    Calipers are used to make extremely precise measurements. Dial calipers are precise to the thousandth of an inch (0.001"). A caliper uses two arms to measure the width of an object or the space between two objects.

  • How to Use a Vernier Caliper

    When highly accurate measurements are needed from a measuring device such as a micrometer, a sliding scale, called a Vernier scale, is used in addition to the usual fixed scale. The Vernier scale refines the accuracy of the measurements by further dividing the lowest subdivision on the fixed scale of a caliper micrometer. For instance, if the smallest increment on the fixed scale was 0.25 mm, then the Vernier scale would have a range of 0.0 to 0.25 mm.

  • Reading the Vernier Calipers

    The Vernier scale on caliper micrometers is the graduated scale that slides as you adjust the calipers. It is calibrated to represent subdivisions of the most precise division on the main scale. For instance, if the main scale is marked every 0.5 mm, the Vernier scale would be divided into sections from 0.0 to 0.5 mm. With a little practice, the Vernier scale is actually very easy to read, once you get used to the small differences as compared to traditional scales.

  • How to Read a Metric Vernier Caliper

    A caliper is a type of micrometer designed to make very precise measurements. The addition of a Vernier scale can make the calipers even more precise and easier to read. On a metric caliper, there are ten divisions on the Vernier scale. These divisions represent the second decimal place, 0.01 mm. Further subdivisions can be added to maker the measurement even more precise. Having these divisions on a separate scale allows them to be spaced farther apart and, therefore, easier to read.
