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 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 thermic 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).

4
 Insert power unit into AC outlet, which shall be easily accessible; after few
seconds the balance will automatically switch on.
 Wait 30 minutes from switch on and then calibrate the balance using the
appropriate mass, following the instructions (par.7)
 Calibrate again the balance every time it’s moved to another place
 Check the balance calibration periodically.
 We recommend not to drop 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.

5 Weighing
After having connected the balance to AC outlet, it will perform an internal circuits test,
after that the balance will set itself in stand-by mode.
5.1 Stand By
From “STAND BY” mode:
 Press ON/OFF button to bring balance to work conditions.
 Press again ON/OFF button to return to “STAND BY” condition.
5.2 Simple weighing
Load the sample to weigh on the pan and read the value on display as soon as the
stability symbol ж(star) appears

6 Calibration
Electronic balances take mass measurements making use of gravity (g). Difference of
latitude in geographic areas and altitude will vary gravity acceleration value (g).
Therefore, for accurate measurements, the balance must be adjusted to the local
environment. This adjustment is accomplished by calibration function.
6.1 External calibration balances
Calibration is accomplished by pressing CAL button.
1. Press CAL button when pan is empty, dashes are displayed on the display.
2. When calibration weight value starts to flash, load the weight on the pan.
3. The display will stop flashing, indicating calibration weight value.
Once the calibration is effected will be shown the value of the calibrated weight and
the current unit of measure.
4. Unload calibration weight from the pan.
The balance is ready for weighing operations.
NOTE: if there is interference during calibration process, an error message will be displayed.
