Standardisation
The chain or tape being used may not be the correct length so it may always over or under read (a systematic error). This can be corrected by:
| L = l x | actual tape length |
| assumed tape length |
| For example: | l | = 226.20 | |
| assumed tape length | = 30.00m | ||
| actual tape length | = 30.005 m | ||
| then: | L | = 226.20 x | 30.005 |
| 30.00 | |||
| = 226.238 m |
A tape is standardized by comparison with a "standard" tape or by measuring a definite "known" distance.
