Tilt error

In length measurement technology, a tilting error or truncation error is the deviation between the measured and actual value. In contrast to random errors, tilt errors are a systematic error. They are the same size under the same conditions, occur regularly and can be detected. They can therefore be compensated for by suitable corrective measures.

Tilt errors are divided into several orders:

• The tilting error of the 1st order occurs most frequently. It is caused by reading at an angle or too high a measuring force , for example with a caliper .
• A tilt error of the 2nd order is caused by an oblique positioning. The measuring instrument and test item are then not exactly aligned.
• The 3rd order tilt error occurs only with optical length measuring instruments , due to their design and mode of operation.
