DATAS READING FROM VERNIER CALIPER WITH GRADUATION 005 MM AND 002 MM The Vernier scale is attached to the caliper's slider and each division on this scale is made 0.05 mm shorter than one main scale division of 1 mm. This means that as the caliper jaws open each successive movement of 0.05 mm brings the succeeding vernier scale line into coincidence with a main scale line and so indicates the number of 0.05 mm units to be counted (although for convenience the scale is numbered in fractions of a mm). Look straight at the vernier graduation line when checking the alignment of vernier graduation lines to the main scale graduation lines. If you look at a vernier graduation line from an oblique direction the apparent al ig nment position is distorted as shown at the figure below due to a parallax effect caused by the step height between the planes of the vernier graduations and the main scale graduations resulting in a reading error of the measured value.
