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 coincide with zero marking.
<div>The simple example to understand the zero error correction is - Consider that a metre scale is broken from its zeroth end and the length of objects are to be measured with the help of same scale. The first visible marking on the broken scale is from 1 cm. So if a length is measured with the broken scale of certain object is 30 cm. Then it will not be the correct length of that object. To get the correct length we need to subtract zero error from that value. As 0-1 cm is missing in that scale. 1 cm has to be subracted from the measured length. So correct length of that of object will be: Measured length - zero error= 30 cm - 1cm= 29 cm&.</div>1Thank You
