Place the material to be measured between the blades of the calipers. Slide the jaws closed until the blades tighten on the material to be measured. Caution must be expressed not to squish the material, in that inaccurate readings will occur. When reading the calipers, the large graduations (labeled 1, 2, 3, 4, etc.) are 100/1000ths of an inch. The smaller graduations are 25/1000ths of an inch. To measure an internal control characteristic use the smaller internal blades on top of the verniers. When using larger calipers, check to make sure that internal blades start at zero.
