Solution
For measuring the length of an object using a vernier caliper, these steps are followed:-
(a). First of all, we find the least count and zero error of the vernier calipers.
(b). Place the object whose length is to be measured below the lower jaws and move the jaw till it touches the object. Record the main reading.
(c). Note the division on the vernier scale that coincides with some division of the main scale. Multiply this number of vernier division with least count. This is vernier scale reading.
(d). Record the observed length by adding the main scale reading and the vernier scale reading. Also, subtract zero error with its proper sign, if any, from the observed length to find the true length of the object.
