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

B): Applies to the four horizontal intersection points

C): The values stated presuppose normal to favourable environmental conditions (e.g. no vibration, no fog, no smoke, no direct sunlight). Extreme fluctuations in temperature can cause deviations in accuracy.

D): An additional deviation of ±0.1 mm/m must be taken into account when at maximum self-levelling range.

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

F): Shorter operating times when operated with Bluetooth®

G): When energy saving mode is switched on

H): 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.

I): 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.).

J): Depends on battery in use

K): Rechargeable batteries, non-rechargeable batteries and their adapters are excluded from the protection rating.

The serial number (16) on the type plate is used to clearly identify your measuring tool.
