1 Installation instruction
WARNING:
Please follow carefully these steps for installing and use the new balance
before starting your work routine. A way of use of the instrument different
from this user manual will not guarantee the instrument’s safety anymore.
Remove the balance, calibration weight( if included) and accessories from the
cartoon and check for any visible damage of the instrument.
Do not install the balance in a place with air flows, heavy thermal changes and
vibrations.
Do not use the balance in blast risk environment.
The humidity rate of the balance environment must be between 45% and 75%
Place the weighing pan and the support pan on the balance (see par. 3).
Level the balance using the level bubble and levelling feet located underneath the
case
Connect power supply to connector 2 located on the rear panel of the unit (see
par. 5).
ATTENTION
In models with internal calibration remove the screw in the left lower
part of the balance (see par.5)

4
Insert power unit into AC outlet, which shall be easily accessible; after few
seconds the balance will automatically switch on.
Balance Warm-up:
Wait 8 hours from switch one for Analytical balanaces (0,0001g)
Wait 30 minutes for other models
Then calibrate the balance using the appropriate mass (if supplied), following
instructions (par.7).
It is strongly suggested not to disconnect the balance from the electrical
mains and to use the ON/OFF button to stand-by the balance when you
finished using it
Calibrate again the balance every time it’s moved to another place
Check balance calibration periodically.
We recommend not dropping heavy objects on balance pan, in order to avoid
damages.
Assistance service must be effected by specialized staff and the spare parts used
must be original. Therefore, it is necessary to apply to the reseller who sold the
equipment.
2 Storage
Storage temperature: +5 °C…+40°C
Storage humidity 45% - 75%.
Keep package in the case the balance should be sent back to the factory for service.
Disconnect the cables and the accessories for avoiding damages during
transportation.
Do not place the balance in extreme temperature and humidity condition and avoid
the balance to take strong hit.
