- A)
- When measuring from the front edge of the measuring tool, this applies for high reflectivity of the target (e.g. a wall painted white), weak background lighting and a 20 °C operating temperature; a distance-dependent deviation of ±0.05 mm/m must additionally be factored in. 
- B)
- When measuring from the front edge of the measuring tool, this applies for high reflectivity of the target (e.g. a wall painted white), strong background lighting, a 20 °C operating temperature and high elevation; a distance-dependent deviation of ±0.15 mm/m must additionally be factored in. 
- C)
- In continuous measurement mode, the max. operating temperature is +40 °C. 
- D)
- Only non-conductive deposits occur, whereby occasional temporary conductivity caused by condensation is expected. 
- E)
- Bluetooth® deactivated 
- F)
- At an operating temperature of 25 °C 
- G)
- After user calibration at 0° and 90°; An additional grade error of ±0.01°/degree to 45° (max.) has to be taken into account. The left-hand side of the measuring tool serves as the reference level for grade measurement. 
- H)
- When using Bluetooth® Low Energy devices, it may not be possible to establish a connection depending on the model and operating system. Bluetooth® tools must support the GATT profile. 
The serial number (11) on the type plate is used to clearly identify your measuring tool.
