6 Unpacking, installation and commissioning

6.1 Place of installation, place of use

The balance is constructed in such a way that reliable weighing results can be

achieved under normal application conditions.

By selecting the correct location for your balance, you will be able to work quickly and

precisely.

Therefore please observe the following at the place of installation:

• 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. In-

admissible bedewing (condensation of air moisture on the device) can occur if

a cold device is taken into a significantly warmer environment. In this case,

please acclimatise the device for approx. 2 hours at room temperature after it

has been disconnected from the mains.

• Avoid static charging of the material to be weighed, weighing container and

windshield.

Major display deviations (incorrect weighing results) are possible if electromagnetic

fields occur as well as due to static charging and instable power supply. It is then

necessary to change the location.

6.2 Unpacking

Carefully remove the balance from its packaging, remove the plastic wrapping and

position the balance in its intended working location.

6.2.1 Installation

Install the balance in such a fashion that the weighing plate is absolutely horizontal.

Please make sure that the transportation lock of the models 440-21N and 440-21A

has been removed before placing the weighing plate.
