A): The working range may be reduced by unfavourable environmental conditions (e.g. direct sunlight).

B): At 20 °C

C): Along the axes

D): At a maximum slope of ±8.5%, the maximum deviation is ±0.2%.

E): Only non-conductive deposits occur, whereby occasional temporary conductivity caused by condensation is expected.

F): When using Bluetooth® Low Energy devices, it may not be possible to establish a connection depending on the model and operating system. Bluetooth® devices must support the SPP profile.

G): The signal range may vary greatly depending on external conditions, including the receiving device used. The Bluetooth® range may be significantly weaker inside closed rooms and through metallic barriers (e.g. walls, shelving units, cases, etc.).

H): Depends on battery in use

I): The measuring tool, mounted in a horizontal position on a tripod, tips on flat concrete floor.

The serial number (21) on the type plate is used to clearly identify your measuring tool.
