Short offsets are measured with an ordinary chain.
With the help of the chain, the outline of the survey lines is measured.
The metallic tape and the cloth are used for the measuring purpose of the short offset that can provide accuracy with zero error.
However, the steel chain is used for the measurement of invar tape or chain length.
