1. BASIC INFORMATION
1.1. Intended use
Balances 3Y series are intended to precise mass measurement of weighed
loads conducted in laboratory conditions. It is designed only for non-automatic
weighing processes, thus the material to be weighed needs to be placed on the
center of balance’s weighing pan with required carefulness.
1.2. Precaution measures
Never use the balance 3Y series is areas endangered with explosion. Balance
3Y series is not designed to operate in EX zones. Do not make any changes in
balance structure.
1.3. Warranty
Warranty does not cover the following cases:
• Balance defects if it is utilized contrary to its intended use,
• Balance defects, if service claims removing or destroying product’s protective
stickers which protect the balance’s housing against unauthorized access.
• Mechanical defects or defects caused by liquids and natural wear,
• Balance defects caused by inappropriate setting of a defect of electric power
network,
• Defects caused by overloading balance’s mechanical measuring system.
1.4. Supervision over balance metrological parameters
Metrological parameters of a balance need to be checked by a user in
determined time intervals. Inspection frequency is conditioned by ambient
conditions in which a balance is used, type of carried out processes and adopted
quality management system.
1.5. Manual significance
It is very important to read the user manual carefully before switching on and
starting up balance operation, even if the user is experienced and has worked
with the this type of balance before.
1.6. Balance user training
A balance should be utilized and supervised only by users who are trained and
experienced in using this type of weighing instruments.

2. TRANSPORT AND STORAGE
2.1. Packaging
Retain all elements of balance packaging in case they are needed for future
balance transporting. Only an original balance packaging can be used for
transporting a balance. Before packaging, disconnect all cables and conductors from
the balance and remove any moveable parts from the weighing chamber (weighing
pan, shields, inserts). Balance components should be packed into their original
packaging for their proper protecting against possible damage during transport.
3. UNPACKING, INSTALLATION AND COMMISSIONING
3.1. Installation and place of use
− Balance should be stored and used in rooms free from any vibrations and
shocks, with no air movement and undusted,
− Ambient air temperature in a weighing room should not exceed the range
specified on balance data plate. Temperature changes should be of laminar
structure, and permissible temperature change ratio should not exceed 0,5
°C/h
− Air humidity should contain within 35% - 80%; maximum humidity change rate
5% / h,
− A balance should be placed on a wall console or a stable workbench, free
from vibrations and distant from heat sources,
− Pay special attention to weighing magnetic materials. In case such loads are
to be weighed, use the option of under-hook weighing. The hook for
assembling an under-hook weighing kit is located in the balance base,
− In case static electricity may have effect on balance indications, ground the
balance using the grounding bolt located at the back side of balance base.
− A microbalance MYA 5/3Y/F1 series is intended to determine mass of filters
with maximum diameter of 160mm.
The material of the tested sample is highly electrostatic, thus it requires
applying special measures protecting against static electricity. In case of
carrying out a weighing process in low humidity conditions, it is advisable to
use an additional air ionizer. Such a large surface of the weighed object, in
case of materials like paper that is highly hygroscopic, causes occurrence of
weighing error of several hundreds of reading intervals. Thus it is highly
important to ensure required ambient conditions for balance operation (such
as those listed in the product folder):

- 8 -
Working temperature: 10-40 °C
Relative air humidity: 45% - 65%
Because of the structure of the objects to be weighed, it may be necessary to
store them in glass containers for eliminating the phenomenon of humidity
absorption. As the value of repeatability error increases along with the
weighing pan diameter, the balance also features an additional regular
weighing pan intended to determine mass of standard materials, and testing
the balance with exclusion of any ambient conditions impact on the weighed
object.

vessel (5) and on stabilization of mass indication press TARE button.
3.3. Balance cleaning
Clean the balance using a damp ch by gentle rubbing any contaminated places.
Remember to remove the weighing pan and its shields from the weighing chamber
before their cleaning.
CAUTION:
Cleaning balance’s weighing pan if installed may damage instrument’s measuring
mechanism.
3.4. Plugging to mains
The balance should be plugged to mains using the original power adapter, which
is balance’s standard equipment. Plug the power adapter’s plug to balance’s socket
located at the back of the housing.
3.4. Connecting peripheral equipment

5. BALANCE LEVELING
The balance 3Y series feature a built-in electronic level sensor that continuously
monitors balance’s level status during its operation. On detecting any level change
the sensor indicates a command for readjusting the level. The level status is
continuously indicated in the upper right corner of balance’s display, next to date and
time.
CAUTION:
The first leveling of a balance using the electronic level can be carried out after 2
hours from plugging the balance to mains. This time interval is needed to thermally
stabilize the measuring section of the level monitoring system. Within this time
interval, the level monitoring pictogram visible in the upper bar of the display is
flashing. After activating the level control function the blue coloured dot of level status
is not displayed in the level control pictogram.

7. WEIGHING
Simple weighing process is carried out using only the buttons located on the
right hand side of the balance terminal. The balance features separate buttons for
zeroing, tarring and generating a printout.
7.1. Zeroing process
Pressing the zeroing button causes determining a new zero point
for a balance. From now on mass of all loads placed on balance
weighing pan (including tare) is determined from this point. After
zeroing the displayed indication, the tare and net (gross) values
equals 0. A good weighing practice requires that before starting a
new process the indication is always zeroed by pressing the
zeroing button, and in particular before determining a tare value.
The zeroing range covers +/- 2% of the maximum capacity of a
balance.
7.2. Tarring process
Press TARE button – pictogram “Net“ appearing on the display
informs that all mass indications are subject to applied tare, and
thus are “net” values.
Note: Tarring negative values is impossible and causes displaying an
error message. In such case zero balance indication and repeat tarring
process.
WEIGHING
Load an object to be weighed on balance weighing pan. On stabilization of
indication read the measured result. If prior to weighing process a TARE was applied,
the display indicates Net pictogram.

- 20 -
7.3. Use of constant tare in weighing
If a weighing process applies a set of the same packages with determined mass
then the balance enables determining a constant tare. On weighing process the
constant tare value is recalled by pressing a dedicated QUICK ACCESS KEY. The
value of indicated measurement result is net, i.e. displayed with already applied
tare.
PROCEDURE – recall tare
o In an optional moment press a
QUICK ACCESS KEY
o The display opens a window with a
list of all saved tare values
o Press name or code of a selected
tare – it is automatically
RECALLED to be used
o The display indicates the tare value
proceeded by a minus sign.
PROCEDURE – save tare
o Press a QUICK ACCESS KEY
o The display opens a window with a
list of all saved tare values
o Press PLUS pictogram
o The tare value is added to the
database of tare values
o Press and hold a bar with tare
name
o the display shows fields related to
the selected tare,
o Give name and code of a tare
xxxxxxxxxxxx
As the number of tare values in use may be high, the balance enables:
− Sorting the database by: name, code
− Selecting database items by: name or code
− Editing and changing items in the database of packages
− Printing database items
− Exporting database items to a .csv file
− Importing database items
PROCEDURE
o In an optional working mode press
grey coloured workspace area
o The display opens a window with
an internal menu
o Scroll down to TARE field
o Press TARE field
Caution:
Menu “Tare“ enables saving values of tares
that are accessible on pressing a Quick
Access Key “Tare”.
