7 Unpacking, Installation and Commissioning
7.1 Installation Site, Location of Use
The balances are designed in a way that reliable weighing results are achieved in
common conditions of use.
You will work accurately and fast, if you select the right location for your balance.
Therefore, observe the following for the installation site:
• Place the balance on a firm, level surface.
• Avoid extreme heat as well as temperature fluctuation caused by installing next
to a radiator or in the direct sunlight.
• Protect the balance against direct draughts due to open windows and doors.
• Avoid jarring during weighing.
• Protect the balance 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 of goods to be weighed or weighing container.
• Do not operate in areas with hazard of explosive material or in potentially
explosive atmospheres due to materials such as gasses, steams, mists or
dusts.
• Keep away chemicals (such as liquids or gasses), which could attack and
damage the balance inside or from outside.
• Keep IP protection of the device.
• In the event of the occurrence of electromagnetic fields, static charges (e.g.,
when weighing / counting plastic parts) and unstable power supply, large display
deviations (incorrect weighing results, as well as damage to the scale) are
possible. In that case, the location must be changed.
