6.2 Unpacking / Installation

Carefully remove the balance from the packaging, remove plastic cover and setup balance at the intended
workstation.
1. Take the balance and supplied accessories (a feeder, pan elements) out of the box.
2. Place the balance on a stable ground not affected by mechanical vibrations and airflows.
3. Level the balance with foot screws so that the air bubble in water-level is in the middle.
4. Plug the adapter to the power socket at the back of the balance.
5. Connect the power adapter to an AC220V ± 10% 50Hz ± 1Hz outlet.

6.3 Mains connection

Before connecting the mains adapter check if the printed voltage value is the same as the local supply
voltage.

6.4 Connection of peripheral devices

The balance may send data to a computer or a printer through RS232C port.
When cooperating with the balance, a computer should be equipped with a program which enables
processing data from the balance.
Before connecting or disconnecting of additional devices (printer, PC) to the data interface, always
disconnect the balance from the power supply.

6.5 Initial Commissioning

In order to obtain exact results with the electronic balances, your balance must have reached the
operating temperature (warming up time 1 hour). During this warming up time the balance must be
connected to the power supply (mains, accumulator or battery).
The accuracy of the balance depends on the local acceleration of gravity.
Please read the information carefully in chap.

"Adjustment".

7 Adjustment
As the acceleration value due to gravity is not the same at every location on earth, each balance must be
coordinated - in compliance with the underlying physical weighing principle - to the existing acceleration
due to gravity at its place of location (only if the balance has not already been adjusted to the location in
the factory). This adjustment process must be carried out for the first commissioning, after each change of
location as well as in case of fluctuating environment temperature. To receive accurate measuring values it
is also recommended to adjust the balance periodically in weighing operation.
