    Slide Calipers Often used to measure the length of an object, the slide caliper provides greater accuracy than the ruler. It can, by virtue of its specially formed jaws, measure both inside and outside dimensions. As the tool’s name ... caliper or on the LCD screen. [Figure 11-41] Some slide calipers also contain a depth gauge for measuring the depth of blind holes. Figure 11-39. Vernier scale readings. Figure 11-40. Dial indicator. Figure 11-41. Electronic…

    Calipers Calipers are used for measuring diameters and distances or for comparing distances and sizes. The three common types of calipers are inside, outside, and hermaphrodite calipers, such as gear tool calipers. [Figure 11-34] Outside calipers are used ... measuring outside dimensions— for example, the diameter of a piece of round stock. Inside calipers have outward curved legs for measuring inside diameters, such as diameters of holes, the distance between two surfaces, the width of slots, and other similar…

    Vernier Scale Some micrometers are equipped with a vernier scale that makes it possible to directly read the fraction of a division that is indicated on the thimble scale. Typical examples of the vernier scale as it applies ... scale is vertical on the right, and the long horizontal lines (0 through 9 and 0) make up the vernier scale. In reading a micrometer, an excellent way to remember the relative scale values is to remember that…
