Do not install the balance in a place with draughts, heavy thermic changes and
vibrations.
Place the weighing pan and the support pan on the balance (see page 4-5).
Level the balance using the level bubble and levelling feet located underneath the
case (see page 7-8 fig. 1a/1b).
Connect power supply to connector 2 located on the rear panel of the unit (see page
7-8).
Insert power cord into AC outlet, which shall be easily accessible; after few
seconds the balance will automatically switch on.
Wait 30 minutes from switch on and calibrate the balance using the mass enclosed
in the package, following the instructions (page 10).
Calibrate the balance again every time it is removed from previous place.
Check 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 seller who sold the equipment.
Keep package in case the balance should be sent back to the factory for service.

EXTERNAL CALIBRATION *
* (For all models except Analytical
balance).
The electronic reading balance takes
measurement of mass making use of
glbctoz
gravity (g). Difference in geographic area
and altitude will vary gravity acceleration
(g). Therefore, for accurate measurement,
scale must be adjusted to the local
environment. This adjustment is
accomplished by CAL key.
At empty pan, press CAL key.

CALIBRATION MODE *
* These functions are available ONLY for models provided with servomotor and internal
calibration mass.
The balance effects mass measurementsmaking use of gravity (g). Differences in geographical
areas and in altitude will vary gravity acceleration (g).
Therefore, in order to have precise measurements, the balancemust be adjusted to local
environment. This adjustment is accomplished by calibration function.
There are 4 calibration modes available :
1. Autocalibration
2. Internal calibration
3. External calibration
4. Technical calibration
1. AUTOCALIBRATION
The balance autocalibrates through internal calibration weight every 30 minutes, after checking by
microprocessorthat other weighing operations are not being effected. In this mode, in additionto a
calibration every 30 minutes, it is possible to effect calibration with internal calibration weight by
pressing CALkey at any time, being sure there is no weight loaded on the pan.
2. INTERNAL CALIBRATION
The balance autocalibrates through internalcalibration weight ONLY on user’s request by pressing
CAL key. Calibration every 30 minutes is excluded.
3. EXTERNAL CALIBRATION
The balance calibrates throughexternal calibration weight (NOT provided on models with internal
calibration weight).
4. TECHNICAL CALIBRATION
This function allows re-storing of internal calibrationweightvalue wheneverinterventionof
assistance-checking-service require it.
ATTENTION : this procedure must be effected using only calibration weight in class E2.
NOTE: for balances NOT provided with servomotorand internal calibration weight, ONLY
EXTERNAL calibration mode is available.

AUTOMATIC UPDATING OF
UNIT WEIGHT
After having effected the sampling, it is
possible to update the average unit weight
as follows :
insteadof loading all the piecesto count,
load a number of pieces equal to the
double of the one loaded on the pan.
Wait for all the arrows to be displayed
followed by a short acoustic message.
Now it is possible to repeat this procedure
up to a maximum of 255 pieces or proceed
to the normal counting of the pieces. This
mechanism grants a more precise
evaluation of the average unit weight and a
better precision in counting of pieces.
NOTE: the mechanism of the automatic
updating is not active if the sampling has
been effected by insertion of the average
unit weight from alphanumeric keyboard.

DETERMINATION OF SOLID DENSITY FOR BALANCES WITH
PROPER OPTIONAL SOFTWARE *
Balance program allows to determine solid density through four steps:
TARE IN AIR;
TARE IN WATER;
SOLID WEIGHING IN AIR;
SOLID WEIGHING IN WATER.
STORAGE OF TARE IN AIR
Tare in air (weight of the small basket in air) is about zeroing of small basket weight in air.
Press TARE key to effect this operation being sure that value displayed is “0”.
STORAGE OF TARE IN WATER
Select density menu by pressing MENU key. The message “DENS” is displayed. By
pressingTARE key the message “t.H20” is displayed. Dip the small basket in water and
press TARE key once again. The message starts flashing until stability is reached, then an
acoustic alarm is given out. Tare value in water is stored until balance is switched off, and it
can be changed repeating the same sequence of operations above mentioned.
DETERMINATION OF SOLID DENSITY
Select“DENS” by pressingMENU key and then press CAL key. The message “S.AIR” will
be displayed. Load a solid in the small basket and pressCAL key. The message starts
flashing. As soon as it is stable, an acoustic alarm is given out and the message “S.H2O” is
displayed. Dip the small basket with the solid in water and press CAL key once again. The
message will flash. As soon as stability is reached, an acoustic alarm is given out and
density value is displayed.
Press MENU key to return to weight display.

SERIAL INTERFACE RS 232
1) General characteristics
The balance sends the value displayed in serial form RS232C, allowing to print weight on
PC monitor or on a serial printer. In case of connection with PC, it is also able to get
commands, always in RS232C format, that allow to effect all operations with balance keys
through PC keyboard. Baud rate is selectable trough MENU andkeys, as
shown previously, at 1200, 2400, 4800, and 9600 baud. The format of character is of 8 bit
preceded by a start bit and followed by a stop bit. Parity is not considered.
1) Interface selection for PC
Selecting PC output (personal computer
IBM compatible) through MENU and
keys, weight is sent continuously at the
same frequency with which weight
indication is updated on display. It is
The connector to use for PC connection is n.1 (fig.1 page 33).
2) Interface selection for printer
Otherwise, if it has been selected output for serial printer, weight value will be printed,
once this will be stable, pressing PRINT key. If weight does not become stable in 10
seconds, the message “ERROR”will be displayed and an acoustic alarm will be emitted.
The connector to use for printer connection is n.1 (fig. 1 page 33).
3) Display format
The string sent is composed of 14 characters: first character : weight symbol (space or -) ;
- second - ninth character : weightor pieces number ; tenth - twelfth character : measure unit symbol ; -
thirteenth character : carriage return ;
- fourteenth character : line feed.
39
Possible non-meaningful zeroes are spaces.

When the balance is in over range condition, weight value transmitted is replaced by
strings “over” and “under” (only if PC output has been selected).
