Why do we use zero correction? Zero correction is used in an instrument for removing the zero error. What is zero error and its correction? Zero error correction arises due to error in the measuring instrument. It occurs when the first marked line of the instrument like vernier calliper, micrometer screw guage etc. do not […]
