3 INSTALLATION
3.1 GENERAL RULES
This instrument will be installed according to the following instructions:
Avoid unstable supporting surfaces and, if necessary, use the special support for wall application,
make sure that the fastening screws have got grip on.
When the instrument is installed in an electric board, make sure that its case does not rest on other
devices included in it.
The connecting leads have to be inserted and screwed onto the internal terminals correctly to avoid
accidental disconnections.
The connecting leads must be laid so that they cannot hamper moving people or machines.
Do not install the instrument near equipment that do not comply with the standards stated by UE
regulations concerning emission of radio-frequency noises.
Avoid any contact of this instrument with corrosive acids.
Do not use sharpened tools to press the buttons of the keyboard.
As regards the installation of the weight detecting system, please comply with the specific
instructions of your own instrument.

EUROBIL
4 OPERATIONAL FUNCTIONS:
4.1 SWITCHING THE INSTRUMENT ON/OFF
Switch the instrument on by pressing the key
All the display units will be enabled for some seconds to undergo an operational check.
Then the display will start the zero search.
After searching zero the display is prepared for weighing operations.
If zero search were unsuccessful, some dashes will appear in the central part of the weight
display.
4.2 AUTOMATIC ZERO SETTING
When the display does not indicate zero, being the plate unloaded and no tare inserted, reset
zero by pressing the key
The resetting range is 2% of the maximum capacity.
4.3 AUTOMATIC TARE
Enable the automatic tare by pressing the key
This operation is carried out in any mode ( NET or PIECES), with positive gross weight lower
than the max. capacity. Then the value is cleared with C and when the instrument is switched
off.
Page 9

EUROBIL
4.4 CLEARING THE TARE
Clear the tare by pressing the key
4.5 SELECTING THE DISPLAY OF NET WEIGHT / PIECES
Pressing the key
will alternately select the display of net weight and pieces (pieces, only if a sampling
operations has been carried out).
4.6 PRINTING THE WEIGHING OPERATION
Pressing the key
will lead to this operation in any mode (NET or PIECES), with positive gross weight lower than
the max. capacity.
4.7 SETTING PRESET TARES
Press the following key
Set the digital value and press ENTER
This operation is carried out in any mode ( NET or PIECES), with positive gross weight lower
than the max. capacity. Then the value is cleared with C and when the instrument is switched
off.
Page 10

EUROBIL
4.8 SELECTING STORED TARES
Pressing the key
will lead to display the message “COD T” for some seconds.
Then set a number (1 to 9) corresponding to a stored tare. Pressing ENTER will confirm the
insertion of this tare.
Press ESC to quit this function
4.9 SETTING CODES
Pressing the key
will lead to display the word “CODE” for some seconds.
Then set a number from 1 to 99. This code is also used to totalize the weighing operations.
Setting the code 0 will lead to totalize the weighing operations only in the grand total.
If the Unitary Average Weight of the code is different from zero (refer to programming
operations), the piece counter will automatically be enabled.
Press ESC to quit this function
4.10
SAMPLING PIECES
Pressing the key
will enter the sampling function (calculation of unitary average weight).
A sampling can be realized through the following steps:
1) load the pieces to be sampled, onto the platform
2) set the number of pieces, with the number keys
3) press ENTER
4) the display will show the UNITARY AVERAGE WEIGHT for some seconds, then the
number of pieces will be displayed
Press ESC to quit this function
Page 11

EUROBIL
4.11 INSERTING THE UNITARY AVERAGE WEIGHT
Pressing the key
will lead to set the known Unitary Average Weight (UAW) [PMU is the acronym of “Peso
Medio Unitario”, that is unitary average weight, in Italian]:
- set the UAW in grams
- confirm this datum (pressing ENTER)
The piece counter is enabled and the display will switch to PIECES.
4.12 PIECE COUNTER
This function will count the pieces by using the unitary average weight of each piece and the
net weight available on the platform (number of pieces = net weight / unitary average weight).
The piece counter is automatically enabled when a sampling operation is carried out or a
unitary average weight is called-up. After enabling this function the display will indicate the
number of pieces. However the operations of semiautomatic zero and tare can be carried out
during this operating mode.
Pressing the key will alternately select the display of the value of net weight – number
of pieces. If pieces are displayed, the pieces are printed and totalized (even by code), at every
weighing operation. The UAW is indicated only in the print.
4.13 PRINTING TOTALS
Pressing the key
will display the word “TOTAL” for 1 second; if the control of products is enabled, the code of
the product to be printed can be set:
- confirming 0 will print all the products, together with non null total and the grand total
- confirming a code will print the total concerning that code.
If the product function is not enabled, only the grand total can be printed.
Now it is possible to choose the following options:
 printing
 printing with reset
 displaying weight total (in kg)
 displaying total of pieces
 reset
Page 12
N.B.:

EUROBIL
• Before starting the operations described above, the instrument will check whether the printer is
on line.
After a printing with reset, the message “ T O T A L S R E S E T” will be printed at the bottom of the
voucher.
If the PRINT protocol is not enabled, the total (net weight or pieces according to what is being
displayed) will be displayed in any case. If a code has been set, the displayed totals will refer to that
code.
Press ESC to quit this function
4.14 DISPLAY TOTAL
This function will displaying weight total or displaying total of pieces refered at the code set
Pressing the key
Shift
0
- will display the word “TOT pes” alternating at WEIGHT TOTAL numeric value
IF the operation mode active is “PCS COUNTER”
- will display the word “TOT pCS” alternating at PIECES TOTAL numeric value
Now it is possible to choose the following options:
 KEY C = CLEAR
 KEY ESC = QUIT whitout clear.
4.15 CHECKING THE CHARGING LEVEL OF THE BATTERY
Pressing the key
will display the charging level of the battery for some seconds. The charging level is indicated
by a number ranging from 1 to 5, according to the supply voltage detected by the instrument.
If the self-switching-off function is enabled, this condition will occur when the weight remains
stably in minimum weighing for the minutes specified, and no key is pressed.
Below a certain charging level, the abbreviation BATT will alternate together with the weight,
on the display, to signal the condition of battery down. The instrument will automatically be
switched off, below a minimum charging threshold.
4.16 LOCKING TARE
Pressing the key
Page 13

EUROBIL
will alternately enable / disable the lock of tare value.
Pressing the key for the first time will lead to display the word “LOCK” for some
seconds, to indicate that the entered tare value is locked; therefore, when the load is removed,
the tare will not be reset.
Pressing the key again will lead to display the word “UNLOCK” for some seconds, to
indicate that the entered tare value is unlocked; therefore, when the load is removed, the tare
will be reset.
5 ENTERING THE PROGRAMMING MENU
Pressing the key
