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

B): At 20–25 °C

C): Applies to the four horizontal intersection points

D): 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.

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

F): Shorter operating times in Bluetooth® operation and/or in conjunction with RM 3

G): 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.

H): 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.).

I): The lithium-ion battery and the AA1 battery adapter are excluded from IP54.

The serial number (18) on the type plate is used to clearly identify your measuring tool.
