Accuracy Check
Regularly check the accuracy of the measuring tool.
Accuracy Check of the Distance Measurement
For the accuracy check, the measurement should be taken under favourable conditions, i.e. the measuring section should be indoors and the target surface for the measurement should be smooth and reflect well (e.g. a white-painted wall).
- Select a measuring section of approx. 3 to 10 m long, the length of which you know exactly (e.g. room width, doorway).
- Measure the section 10 times in succession.
- The deviation of individual measurements from the exact known value may be maximum ±2.5 mm throughout the entire measuring section under favourable conditions. Log the measurements, so that you can compare their accuracy at a later point of time.
