3.3 Assembling your weighing machine
The weighing machine is delivered in partly dismantled condition. Assemble the
individual components in the following sequence:
 Place the unit holder in position and add the weighing pan
 Insert the power adapter cable plug into the socket at the rear of the
balance.
3.4 Choice of a suitable location
The environment in which your weighing machine is used is very important. Air
movement, temperature changes, vibrations, direct sunlight, etc. all influence
the performance of high precision weighing machines. Therefore, place your
weighing machine on a solid, sturdy surface that is free of air currents, vibration
and not in direct sunlight. The surface should not be magnetic and should be
located away from doors, windows, heaters, air conditioners and fans.
To summarize:

Put the weighing machine on a solid, firm and preferably
vibration-proof, horizontal base
 Make sure that the weighing machine cannot be shaken or knocked
over
 Protect from direct solar radiation
 Avoid drafts and excessive temperature fluctuations
3.5 Checking the mains voltage
The following Safety recommendations must be observed when connecting the
balance to the mains:
The balance may only be operated with the power adapter supplied.
Check before connecting the power adapter to the mains supply, that the
operating voltage stated on the power adapter agrees with the local mains
voltage.
If the operating voltage is not the same as the mains voltage, the power adapter
must on no account be connected to the mains supply. Contact customer
service.
