Consider the following case where the zero of vernier scale and the zero of the main scale are clearly seen. If L.C. of the vernier calipers is 0.01 cm, write the zero error and zero correction of the following.
उत्तर
Here, zero of the vernier scale lies on the right of the zero of the main scale.
Also, the 5th vernier division is coinciding with some main scale division
Thus, zero error = 0 + 5 x L.C. = 0.05 cm
Hence zero correction = -0.05 cm
