all the object vertically in the external Jaws of the calipers tightly such that the external Jaws are at the right angle to cut surface of the object
determine the position of the zero of the Vernier Calliper on the main scale and hands record the number of divisions on the main scale before zero
look what the vernier scale Division with concert with any of the main scale division record the number of vernier scale coincide with the main scale
repeat the experiment three times more by turning the object about its vertical axis
calculate the length of the object in each case by applying the formula
length of the object is equals to main scale division * pitch + vernier scale division * least count
hope it helps you
