Tension
A tape is a given length when pulled with a certain tension. If the tension changes then so does the tape length. The correction is as follows:
| DL= | l x DT |
| E x A |
where DT is the change in tension and A is the cross-sectional area.
However, it is far simpler to pull the tape at the correct tension and eliminate this altogether.
