2. BASIC INFORMATION
2.1. Intended use
Precision balance PS/X series is designed to determining the weighing value of loads
in laboratory environment. It is intended for application as a non-automatic weighing
instrument only, i.e. the material to be weighed should be manually and carefully
placed in the center of the weighing pan. Weighing result should be read only after
stable reading has been obtained – stability pictogram is visible on balance’s display.
2.2. Inappropriate use
Do not use the balance as a dynamic weighing instrument. Even if small quantities of
weighed material are added or removed from the weighing pan of the instrument, the
reading should be taken only after stabilization of the measurement result. Do not
place any magnetic materials on the weighing pan, as this can cause damage of the
measuring system of the instrument. Be sure to avoid impact shock and overloading
the balance in excess of the prescribed maximum measuring range (max capacity),
minus any possible tare weight that has been applied. Never use the balance in an
environment endangered by an explosion. This balance has not been adjusted for
operation in explosive areas. There must not be any modification made to the balance.
2.3. Warranty
Warranty is not valid at the following:
• Non-observation of the guidelines of this user manual,
• Use of balance other than specified in this manual,
• Alternation to or opening of the device (damaged of the protective stickers),
• Mechanical damage and damage caused by media, natural water, and tear,
• Inappropriate assembling or defects of electric installation,
• Overloading of the measuring instrument.
2.4. Monitoring metrological parameters of the balance
Metrological characteristics of the balance requires periodical inspection carried out by
its operator. Inspection frequency is conditioned by ambient conditions in which the
balance is used, types of performed processes and accepted quality management
system in an organization.

- 8 -
2.5. Data included in this user manual
Please read the user manual carefully before assembling and startup, even if the user
is experienced with this type of weighing instruments.
2.6. Staff training
This balance should only be operated and maintained by personnel who is trained and
experienced in using this type of balances.
3. TRANSPORT AND STORAGE
3.1. Delivery check
Please check the packaging immediately upon delivery and the device during
unpacking for any visible signs of external damage.
3.2. Packaging
Please retain all parts of the original packaging should the balance be transported in
the future. Only the original packaging should be used for dispatching the balance.
Before packing, disconnect all attached cables and remove any loose/movable parts
(weighing pan, anti-draft shields, etc.). Please place balance and its components in
their original packaging, and protect them against damage during transport.

- 9 -
4. UNPACKING, ASSEMBLING AND STARTUP
4.1. Assembling and place of use
• Balance should be stored and used in locations free of vibrations and shakes, free
of air movement and dust,
• Ambient air temperature should not exceed the range of: +10oC ÷ +40oC
• During balance operation, ambient temperature in the weighing room should not
change more than 3°C within one hour,
• The balance should be located on a stable wall console desk or a stable working
table which is not affected by vibrations and distant from heat sources,
• Take special safety measures when weighing magnetic objects, as part of the
balance is a strong magnet. Should such loads be weighed, use under hook
weighing option, which removes the weighed load from area influenced by the
balance’s magnet. For assembling the hook for under hook weighing option see the
bottom section of balance’s housing,
• In order to avoid influence of static electricity on the measurement process, ground
the balance’s housing. The grounding bolt is located at the back of balance’s
housing.

- 10 -
4.2. Unpacking
Carefully remove the balance from its packaging, remove the plastic, foil and
cardboard transport protective elements and gently place the balance in its intended
place of use. Assemble the weighing pan, and other elements according to below
scheme:
Assembling components of a balance with measuring accuracy 10 mg:
- Remove the protective tape securing
the mass spring on one of the rubber
mandrels (2),
- Assembly the weighing pan (1) onto
the rubber mandrels (3),
- On assembling check whether the
weighing pan is placed firmly on the
rubber mandrels.
Assembling components of a balance with measuring accuracy 1mg:
- Remove the protective tape securing the
mass spring on one of the rubber
mandrels (3),
- Assembly the weighing pan (2) onto the
rubber mandrels (4),
- Assembly the anti-draft shield (1) onto
the top housing of the balance,
- On assembling check whether the
weighing pan is placed firmly on the
rubber mandrels.

- 11 -
4.3. Leveling
Before plugging to mains, level the device using two adjusting feet
located at the back of balance’s housing. Turn the adjusting feet in a
way that the air bubble of the level is placed centrally. The level is
located at the back wall of balance’s housing.
4.4. Standard equipment
• Balance.
• Weighing pan and protecting (anti-draft) components.
• Power adapter.
• User manual on a CD.
4.5. Cleaning
Balance should be cleaned with damp cloth by gentle wiping the smudges of dirt. In
order to clean the weighing pan of the balance, it is required to remove it from the
weighing chamber.
CAUTION!!!
Cleaning of the pan when assembled may cause damage of the measuring
system of the balance.
4.6. Plugging to mains
Balance can be plugged to mains only with a power adapter that comes
standard with the balance. Nominal power supply of the power adapter
(specified on the data plate of the power adapter) should be compatible to the
power from mains.
Plug the balance to mains – the plugging socket is located at the back of balance’s
housing. Balance display will light and show name and number of software, after
which balance will display 0.000g (for balances with resolution 1mg) or 0.00g (for
balances with resolution 10mg).
If indication is other than zero, press ZERO/TARE key.
Before unplugging the balance from mains it is obligatory to switch off the display
by pressing ON/OFF key on balance’s overlay.
4.7. Connecting peripheral devices
The balance must be unplugged from the mains before connecting or disconnecting
any peripheral devices (printer, PC computer). Use only peripheral devices
recommended by the manufacturer with your balance. These have been ideally
coordinated to your balance. On connecting a peripheral device, plug the balance to
mains.

5. BASIC FUNCTIONS
Balance PS/X series enables determining mass in the following measuring units:
Fig. 2. Measuring units
Apart from determining mass of weighed object using different measuring units, the
software balance PS/X series comprises the following working modes:
− Parts counting
− Checkweighing
− Dosing
− Percent setup
− Animal weighing
− Determining density of solids and liquids
− Formulation
− Statistics from completed measuring series
Both the measuring units and the working modes can be set as inaccessible in the
user menu. This option is implemented for the purpose of adjusting balance to user needs
and requirements, i.e. providing access only to those functions and units which are
required by a user.
Determining accessibility attribute of a working mode / measuring unit is set in
balance’s menu and it is described further in this user manual.
