5 Unpacking, Setup and Commissioning
5.1 Installation Site, Location of Use
The unit is designed to achieve reliable display results under normal conditions of
use.
Therefore, observe the following for the installation site:
•Protect the unit against severe vibrations;
•Protect the appliance against high humidity, vapours and dust;
•Do not expose the device to extreme dampness for longer periods of time.
Non-permitted condensation (condensation of air humidity on the appliance)
may occur if a cold appliance is taken to a considerably warmer environment.
In this case, acclimatize the disconnected appliance for ca. 2 hours at room
temperature.
•Avoid static charge.
Major display deviations (incorrect weighing results) may be experienced should
electromagnetic fields (e.g. due to mobile phones or radio equipment), static
electricity accumulations or instable power supply occur. Change location or remove
source of interference.
5.2 Unpacking
Carefully take the unit out of the packaging, remove the plastic jacket and mount the
second display unit at the intended workplace.
5.2.1 Scope of delivery
