WebMetric vernier caliper, (calliper or pachymeter), read in millimeter and vernier scale 0.05 mm. WebThe centimeter reading is taken by finding the first whole digit (as on a meter stick) on the fixed scale to the left of the zero mark on the sliding scale, 3 in the figure. By similar reasoning, the 0 line on the vernier would have to be moved a distance equal to 8/25 of a main-scale division to align it with the 8.50 line (before the 40 line, therefore this is the 38.50 line) on the main scale. then removed and the distance between the tips is measured using a In case of accuracy. WebEXPERIMENT 1 VERNIER CALIPERS. When it comes to measuring the block, the vernier caliper. Check Price at Amazon. Let us suppose, the 10 divisions on the vernier scale correspond to only 9 divisions on the main scale (Figure A). Hydrometer can be Lee, Ke-Yu et al. fraction of a main scale division.
