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
8
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.
9
Moreover, it is possible to calibrate the balance with a calibration weight higher than the
one set by default:
1. Press and keep CAL button pressed with empty pan until the acoustic alarm
stops, then release the button. On display it will be visualized the string "-CAL-",
followed by flashing string "LOAD".
2. Load on the pan a weight equal higher or lower than default calibration weight; the
balance will recognize it as valid weight if equal or higher than calibration weight
as long as it is a whole number in comparison with the most meaningful digit of
calibration weight .
e.g.: if calibration weight is 200g, it will be possible to calibrate the balance with
values from 100g 200g, 300g, 400g up to the highest limit of balance weighing
range.
The message “LOAD” on display will stop flashing. Once calibration has been
effected, the value of calibrated weight will be displayed.
3. Unload calibration weight. The balance is ready for weighing operations.
NOTE: if there is an interference during calibration process, an error message will be displayed.

7 Tare function
1. Load the container on the pan. The display will show the weight.
2. Press O/T button. “O-t” string will be displayed
3. After reaching stability, the value “0.000” will be displayed. If the stability is not
reached (due to air flows or vibrations or other disturbs) the dashes will remain
displayed.
4. Load the objects to weigh in the container. Read net weight value on display.
11
7.1 Manual tare function
This function allow to insert manually the tare values.
1. Press and keep pressed the O/T key whit no objects on the weighing pan until the
beep alarm stops, then release the key.
2. Will be shown on the display the following string:
3. Insert now the desired tare value using the keys CAL and MENU for increase or
decrease the value, and press the O/T key for skip to the following digit. During the
value insert mode, if keep pressed the O/T key is possible to delete the inserted
value.
4. Press PRINT key to confirm the value inserted.

7.2 Optional alphanumeric external keyboard
(code T201)
If you have the optional external alphanumeric keyboard, then it is possible to perform
tare also by pressing the TARE/DELETE button of this keyboard, in the same way as
previously described.
It’s also possible to manually insert a known tare value by the keypad.
1. Press TARE MAN button on the alphanumeric keyboard. An arrow will appear on the
balance display along with the previous value of manual tare, if one has been
inserted before.
13
2. Press CLEAR to set at zero the previous value (if any) then insert the new value
using the alphanumeric buttons placed on the bottom part of alphanumeric keyboard.
3. Press INSER to confirm.
4. Press ESCAPE button to escape from tare condition.
To set to zero the value of the manual tare inserted by means of alphanumeric keyboard,
effect a normal operation of tare by pressing O/T button of the balance or with
TARE/DELETE button placed on the optional alphanumeric keyboard.

8 Weighing units
It is possible to select the weight unit that balance will use to display weight.
1. From display zero condition press and keep pressed the MENU button until the
acoustic alarm is over, then release the button. The message “unitS” will be
displayed then press PRINT to confirm.
2. It will be displayed “GRAM” unit. Pressing now the MENU or CAL button, it will be
possible to scroll forward or backward the weight units menu.
3. Press PRINT button to confirm or MENU button to shift to the other weight unit.
