Fouten bij het gebruiken van een meetlint

Errors occur when the tape is misaligned. A skilled rear tapeman can use an instrument telescope to align the head tapeman accurately, ensuring the tape stays properly aligned.

Human imperfections prevent tapemen from reading tapes or setting pins precisely. While reading and setting errors are minor, plumbing errors can lead to more significant inaccuracies.

Tapemen commonly misread numbers, such as mistaking a six for a nine or vice versa. This becomes more frequent as tapes age, and the numbers wear.

To prevent endpoint errors, tapemen should carefully inspect the tape before measuring, as some tapes have starting and ending points set slightly inward.

A tape sags into a curve when supported only at its ends, reducing the horizontal distance between its ends compared to full-length support.

The sag error can be corrected by subtracting the sag correction from the measured length.

Miscellaneous errors impacting taping precision include wind blowing the plumb bobs, wind pushing the tape sideways, and taping pins not set precisely where plumb bobs touch the ground.
