any separable components (weighing pan, shields, inserts). Pack the device components into an
original packaging. The original packaging protects the equipment against potential damage during
transportation.
3. UNPACKING AND INSTALLATION
3.1. PLACE OF USE AND ASSEMBLING
• The balance has to be stored and used in locations free of vibrations and shakes, free of air
movement and dust.
• Ambient air temperature cannot exceed the range of: +10 °C ÷ +40 °C.
• Ambient relative humidity cannot exceed 80%.
• During balance operation, ambient temperature in the weighing room cannot change rapidly.
• The balance has to 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 precaution when weighing magnetic objects, as part of the balance is a strong
magnet. Should such loads be weighed, use under-pan weighing option, which removes the
weighed load from area influenced by the balance’s magnet. The hook for under-pan weighing
is installed in balance’s base.
3.2. UNPACKING
Cut the adhesive tape. Take the device out of the packaging. Open the accessory box, take the
device components out of it.

3.4. MAIN TE N ANCE ACTI VI TI ES
CAUTION!
Cleaning anti-draft chamber while still installed may cause damage of the measuring system.
1. Disassembly a weighing pan and other detachable components (the components differ
depending on a balance type – see Unpacking and Installation section). Be careful while
detaching the components so as not to cause any damages to the balance mechanism. It is
recommended to use tweezers while detaching microbalance’s pan.
2. Using handheld vacuum cleaner remove dust from the weighing chamber (recommended
especially for microbalances).
3. You can disassembly anti-draft chamber panes of XA and AS series is order to clean them
properly – for disassembly instruction read below.
Cleaning anti-draft chamber panes:
Select dissolvent depending on a dirt. Never soak the glass panes in alkaline solutions since they
interact with glass and may cause damage. Do not use abrasive substances.
For organic dirt use acetone first, next use water or detergent. For other than organic dirt use diluted
acid solutions (soluble salts of hydrochloric or nitric acid) or base solutions (ammonium or sodium
base).
To remove ACIDS use protofilic solvent (sodium carbonate), to remove BASE use protogenic solvent
(mineral acid of various concentration).
In case of heavy contamination use brush or detergent nevertheless avoid detergents containing
large and hard molecules which could potentially scratch glass panes.
Use soft brush with wooden or plastic handle exclusively to avaoid risk of s cratches. Do not use wire
brush.
At the end of the cleaning process rinse the pane using running water first, distilled ne xt .
- 17 -
Page 18
Rinsing is a necessary cleaning process stage allowing to remove remaining soap, detergents and
other cleansers from the panes prior their reinstallation.
Avoid drying the panes either using paper towel or forced air circulat ion since some fibres, grains or
contamination of other type could permeate into the panes thus causing weighing errors.
One shall not use driers when drying measuring glass tools.
It is a frequent treatment to leave glass components on a rack to dry.
Cleaning powder-coated components:
For preliminary cleaning stage you need running water or wet sponge featuring large w holes, this w ill
help you to remove loose, heavy dirt.
Do not use cleansers containning abrasive substances.
Next using cloth and cleanser-water solution (soap, dishwashing liquid) gently rub the cleaned
surface.
Avoid using cleanser without water since it may result with damage of the cleaned surface, please
mind that large amount of water mixed with cleanser is a must.
Cleaning aluminium components:
While cleaning aluminium components use products acid by nature, e.g. spirit vinegar, lemon. Do not
use abrasive substances. Avoid using hard brush, this may cause scratches. It is recommended to
use microfibre cloth.
While polishing the surface use circular movements. Use clean, dry cloth
.
Cleaning stainless steel components:
Avoid using cleansers containing any corrosive chemicals, e.g. bleach (containing chlorine). Do not
use abrasive substances. Always remove the dirt using microfiber cloth to avoid damage of protective
coating.
In case of a daily maintenance:
1. Remove the dirt using cloth dipped in warm water.
2. For best results, add a little dishwashing detergent.
Cleaning ABS components:
To clean dry surfaces and avoid smutching use clean non-colouring cloths made of cellulose or
cotton. You can use a solution of water and detergent (soap, dishwashing detergent, glass cleaner).
Gently rub the cleaned surface and let it dry. Repeat cleaning process if needed.
In the case when contamination is hard to remove, e.g. adhesive, rubber, resin, polyurethane foam
residues etc., you can use a special cleaning agents based on a mixture of aliphatic hydrocarbons
that do not dissolve plastics. Before using the cleanser f or all surfaces we recommend carrying out
tests. Do not use products containing abrasive substances.

Thus prepared anti-draft chamber and panes can be properly cleaned. All the operations have t o be
done carefully. Pay special attention t o the spot where the weighing pan is installed: dirt and other
small elements might enter the balance construction through this opening, which might negatively
influence the balance parameters.
Upon completion of the cleaning process assembly the balance, take actions like before but in a
reverse order. Pay a special attention to the left and the right side pane, assembly it on the correct
side of the balance. While sliding the pane back onto its place remember to pull the protection (like
before when dismantling the anti-draft chamber).
3.5. POWERING THE DEVICE
The balance has to be plugged to the mains using the original power adapter exclusively. Nominal
power supply of the power adapter (specified on t he power adapter data plate) has to be compat ible
to the power from the mains. Plug the power adapter’s to the power supply socket located at the back
of the housing.
3.6. TEMPERATURE STABILIZATION
Before measurement it is necessary to wait until the balance reaches thermal stabilisation.
For balances that were stored in much lower temperatures before plugging to the mains, thermal
stabilisation period shall take at least 12 hours. During the thermal stabilization, t he indications on a
display panel can change. It is recommended that ambient temperature changes at place of use were
insignificant (slow to change).
3.7. CONNECTING PERI PHERAL EQUIPMENT
Use only accessories and peripheral equipment recommended by the manufacturer. The balance
must be unplugged before connecting or disconnecting any peripherals (printer, PC computer,
computer keyboard). On connecting the peripherals, plug the balance to the mains.
3.8. B ALANCES FEATURI NG TERMINAL-WEIGHING MODULE WIR ELESS CONNECTION
(an option)
The terminal operates on batteries, wireless connection ensures its cooperation with the weighing
module. This, in contrast to a standard design, allows to eliminate cable connecting the devices.
Wireless connection solution is marked by letter <B>, e.g. XA 220.4Y.B.
Features:
Maximum range: 10 m
Maximum operation time of the terminal (without the necessity to charge batteries): 8 h
Advantages:
1. Lack of additional sources of vibration
Terminal located elsewhere than the weighing table eliminates vibrations being a result of
operation. This ensures stable working conditions for balances with the highest resolution. No
specific weighing workstations are needed.
2. Comfort of weighing in fume cupboards and laminar flow cabinets

3. Elimination of unfavourable influence factors
Due to wireless connection the weighing module may be completely separated from the
operator by being placed in an anti-draft chamber. This makes weighing of contaminated and
toxic substances possible without putting one’s health and life to risk.
4. Improved pipetting ergonomics
Pipettes calibration process requires precision and quickness of operation. Wireless
connection redefines comfort of operation and guarantees high measurement accuracy.
Wireless solutions are equipped with 2 power suppliers. One used for supplying the weighing
module, the other for powering the terminal.
3.8.1. Start-up Procedure
On unpacking and placing the balance onto its workstation it is necessary to connect the weighing
module and the terminal to the mains. Next proceed like in case of a standard design (description to

In order to ensure long lasting use of a balance plus correct and reliable measurement of weighed
loads, follow below procedures:
• Start the balance with no load on the weighing pan (permissible value of load on the weighing
pan on balance start is ±10% of its maximum capacity).
• Load the weighing pan steadily avoiding shocks:
• Place weighed loads centrally on the weighing pan:
• Avoid side loading, in particular side shocks:

15.6. USE OF AIR BUOYANCY COMPENSATIO N FACTOR
The application enables correcting mass measurement errors in the course of:
1. weighing loads of density considerably different from the density of standard that has been
used to adjust the balance; typically the balance is adjusted with a steel mass standard with
density ~8.0g/cm3 or a brass mass standard with density ~8.7g/cm3; if loads made of other
substances are weighed, then ratio indicated on below chart applies.
Error value in relation to density of weighed sample

2. testing sample mass change within a few hours long period of time for a case when the sample
mass is relatively constant (minor changes); it is assumed that air density changes affect
- 46 -
Page 47
considerably the final result, wherein the density is influenced by changes of pressure,
temperature and humidity.
In order to carry out a reliable measurement it is necess ar y to know the measuring methods, features
of tested sample, air density in the laboratory room and density of weighed sample.
Functioning
The air buoyancy compensation procedure is to be used as follows:
1. Method 1:
Enter air density value and value of weighed sample density to balance’s memory. Wait, the
software automatically calculates the correction factor for weighed mass, next corrected value
of weighed mass is displayed. In order to avoid mistakes, the corrected mass value is
accompanied by <!> symbol, the symbol is visible on a display and a printout.
2. Method 2:
Determine air density value with use of balance software (semi-automatic operation) and enter
value of weighed sample density to balance’s memory.
Determination of air density is carried out using a set of two mass standards, one made of
stainless steel, and the other one of aluminum. Based on mass indications of the two
standards, the software automatically calculates the air density and saves the value in
balance’s memory on operator’s confirmation. Now, enter value of weighed sample density to
balance’s memory. Wait, the software automatically calculates the correction factor for weighed
mass, next corrected value of weighed mass is displayed. The corrected mass value is
accompanied by <!> symbol, the symbol is visible on a display and a printout.
In order to enable/disable the air buoyancy compensation procedure go to the user menu. The
procedure is valid for weighing mode exclusively.
Air Buoyancy Compensation Start-Up
Procedure:
1. Enter home screen and press grey workspace.
2. Select <Settings> parameter.
3. Select <
Air buoyancy compensation> parameter.
Parameter values:
• Air buoyancy compensation – YES/NO.
• Sample density (enter value of weighed sample density). If you use products from
databases, then on product selection its density value is automatically uploaded.
• Air density – parameter designed to enable selecting the method of entering the air
density value.
PARAMETER VALUES:
VALUE – select to open a window where you enter specified air density value (e.g.: determined by
means of other m ethods). The entered value is used in the course of compensation. It is assigned
automatically upon completed air density determination after <
> key has been pressed.
ONLINE – select to make the balance acquir e air density value from a connected THB sensor at a
real time, if such is connected to the balance, or from internal sensor installed in the balance.
If your balance features both types of sensors (THB module and internal sensor), t hen data from the
THB module supersedes the other, in such case go to Setup/Ambient Conditions/Ambient
Conditions Module and set SAVE or SAVE & ALERTS parameter.
If your balance features only one se t of sensors recording temperature, humidity and pressure, then
correct ONLINE operation requires setting the following parameters:
• int ernal sensors exclusively – go to Setup/Ambient Conditions/Ambient Conditions Module
and set NONE value,
• external THB module exclusively – go to Setup/Ambient Conditions/Ambient Conditions
Module and set SAVE or SAVE & ALERTS value.
- 47 -
Page 48
For correct balance cooperation with the THB module it is necessary to set port’s transmission
parameters, they must be com patible with those of the T HB module. The THB module transmission
parameters are detailed on its data plate.
On returning to the weighing mode, the display indicates an additional symbol <
!>, as indicated on
the figure below. From now on the value of indicated mass is corrected including the air buoyancy
compensation factor and sample density.
The measurement result can only be compensated by a correct value if the operator enters the actual
value of the air density and correct value of weighed sample density to balance’s memory.
CAUTION!
If the <AIR BUOYAN CY COMPENSATION > parameter is set to <ONLINE > parameter, then pictogram <!> is
not displayed. This mea ns that parameter Setup/Ambient Conditions/Ambient Conditions Module is set to
SAVE or SAVE & ALERTS value, and that there is no physical connection between a balance and a THB
module, or that balance-modu le communication para meters are incorrect. In suc h case plug a THB module to
balance’s ports CO M 1 or COM 2 and set appro priate communicati on parameters, for the parameters refer to
a data plate.

15.10.
AMBIENT CONDITIONS - VIBRATIONS
Vibrations are a major cause of errors. Since the vibrations spread in all directions, the
vibrations analysers and meters must carry out measurement in three axes concurrently.
Ambient conditions module implemented in RADWAG balances of 4Y series features such
option.
Analytical balances are precise weighing instruments therefore even insignificant oscillations
influence their operation. Humans are most often unable to sense vibrations. In order to
detect them, it is necessary to use special equipment. Vibrations sensor, along with a
module that analyses the influence of the vibrations onto the measurement, informs the user
in a real time on the possibility of occurrence of error caused by high-frequency vibrations.
Usually the vibrations are dampened with use of anti-vibration tables. Signalling device, i.e.
ambient conditions module equipped with a vibrations sensor, is used to support the process
of vibrations dampening. Such device comes standard with each 4Y series balance. With
use of the said signalling device it is possible to evaluate workstation conditions and if
necessary to find more convenient place of use. It is often impossible to find a place where
no vibrations occur, however the signalling device allows the operator to determine when
and where to expect vibrations of the lowest-frequency.
Due to the following 3 factors: specified values of free vibrations, resolution, and permissible
weighing instrument errors, the analysis must be carried out with regard to the right effective
value (rms value) and bandwidth. Such analysis is performed on each 4Y series balance in a
real time.
When it comes to a module applied in RADWAG-manufactured balances, the filters pass
frequencies to which balances are sensitive. In case of balances, effective value (rms value)
measured from 3 axes and for a particular time interval is given, such value provides
information on amplitu de and hi st or y of dist ur banc es .

Radwag has designed analysis method and selected permissible vibrations thresholds
respectively to make signalling device operation both effective and convenient (not
troublesome). Balance screen displays balance-registered vibrations level in percent.
Vibrations threshold cannot be changed, however the operator can modify settings in a way
ensuring that alerts are displayed in the most convenient way, depending on the needs. By
default the set value is 100%.
Example of settings modification:
For better understanding, analyse the following example (the values used below are
exemplary ones, they were not taken form the balance).
Assumed vibrations threshold set by default on 4Y series balance: 100mm/s2.
1.
Max vibrations value: 100% (alert display threshold – pictogram colour change, from
2.
green to red). Pictogram colour is green for vibrations within 0 - 100mm/s2 range, for
vibrations val ue of 101mm/ s2, the pictogram changes to red.
Max vibrations value: 150%. Pictogram colour is green for vibrations within 0 - 150mm/s
3.
2
range, for vibrations value of 151mm/s2, the pictogram changes to red.
Vibrations are signalled by a respective pictogram displayed in the weighing result window.
- 53 -
Page 54
Upon pressing vibrations pictogram, window with current values measured by sensors is
displayed. Displayed vibrations value (IS V) is the effective value registered within the most
recent 2 seconds. This value id refreshed every 2 seconds. If the screen displays 100%
value, this means that vibrations have reached threshold set by RADWAG.
Vibrations are recorded in the database, this allows to analyse history of ambient conditions
quality.
Effective value of vibrations registered by the balance over a declared time interval is saved
(from the moment of the last record) – Setup/Ambient conditions/Ambient conditions
recording interval.
- 54 -
Page 55
By default the interval is set to 10 min, this value may range between 1 min - 60 min. Record
analysis allow the user to select the most optimal time of the day for the measurements
performance, i.e. time when the environmental conditions influence the vibrations the least.
Mind that there are places where the most convenient working conditions occur after-hours.
Along with each measurement, data on ambient conditions alerts and level of vibrations, that
occurred in the course of the measurement, is saved.

24. PIPETTES CALIBRATION
Balance allows for pipettes calibration. In order to calibrate pipettes by means of 4Y balance you
need to use dedicated balance software function or “Pipettes” PC software intended for pipettes
calibration (workstation for pipettes calibration).
Prior to calibration start install pipettes calibration set inside the anti-draft chamber. The set is nonstandard balance equipment.

Installation procedure:
Balance with pipette calibration set installed.
MYA 4Y balance with a set for pipettes calibration:
1. Dismantle the weighing pan and the anti-draft chamber
2. Place the following elements inside:
• anti-anti-draft chamber (1)
• bottom ring (2)
• weighing pan (3)
• glass vessel (5)
• evaporation ring (6)
• glass cover (7)
• supplement ary cover (8)
• or glass cover (4)
XA 4Y balance with a set for pipettes calibration:
Installation procedure:
1. dismantle the weighing pan and the anti-draft chamber,
2. place centering ring (8) inside the chamber,
3. put glass ring (7) onto the centering ring,
4. place weighing pan (6) inside the glass ring,
5. put top ring (5) onto the glass ring,
6. put evaporation ring (4) onto the top ring (5)
7. insert calibration vessel (3) into the evaporation ring,
8. put the glass cover (2) onto the top ring,
9. put glass supplementary cover (1) onto the glass cover.
- 83 -
Page 84
Evaporation ring minimizes measurement errors being a result of liquid evaporation occurring in the
course of the weighing process.
Prior pipettes calibration distilled water must be poured into the evaporation r ing, the amount of water
cannot exceed 2/3 of the ring height.
The set may be operated after about an hour – this period of time is required for humidity
stabilisation. Remember to control the level of distilled water – surface of the vessel has to remain
covered with it. Excess of water may be removed by means of an automatic pump or an external
pipette.
In order to minimize both changes of moisture content inside the weighing chamber and negative
effect of air blows during opening the chamber door, the liquid has to be dosed by means of pipette
through an opening located in the top cover of the weighing chamber.
It is allowed to use a balance without a anti-draft chamber for pipettes calibration. For this reason
both the anti-draft chamber and frame must be dismounted (only XA.4Y.A series balances). For
instruction on anti-draft chamber disassembly read section 3, for instruction on frame disassembly
read below.
In order to remove frame undo 4 screws fixing it to the housing (see the picture). Now you can install
pipette calibration set, follow the above instruction.
Balance with disassembled anti-draft chamber and with installed calibration set.

With thus prepared balance you can start pipettes calibration procedure.
<
Pipette calibration> is a working mode allowing you to determine measurement errors of
piston pipettes volume, the errors can be determined either with reference to ISO 8655 standard or
your requirements.
In case of calibration carried out with reference to ISO 8655 standard t he errors are automatically
selected for particular volume, as specified in the standard (see table of errors, ISO 8655 standard).
Pipette calibration mode enables:
• Calibrat ing pipettes with fixed or adjustable volume, single or multi- channel.
• Pr eparing a pipettes database providing the following information: pipette name, code, tested
volume, etc.
• Calculating results on the basis of:
• Average volume of a pipette (channel)
• Systematic error es (accuracy error)
• Random error CV (repeatability error)
• Car r ying out automated measuring procedures conditioned by pipette’s type.
• St oring calibration results in a database (in a form of reports on calibration process).
• Pr int ing r eports on pipette calibration process.
• Exporting test reports.
During volume testing procedure, the software determines accuracy and repeatability errors for the
tested volume.
In case of pipettes with adjustable volume, the software enables declaring up to 5 volume values
(from total pipette’s range) that are to be checked during calibration process.
For pipettes calibration use distilled water exclusively.
In order to ensure the highest accuracy of pipettes calibration process, maintain the following
ambient conditions at a workstation:
• Ambient temperature of a pipette, tips and liquid has to range between 20°C - 25°C with
change rate during the test ± 0.5°C,
• Relat ive humidity 50 - 75%,
and
• Make sur e that a pipette, tips and distilled water are subjected to thermal stabilization in the
weighing room. Respective standard recommends 2-hour long acclimatization period.
While calibrating pipettes use pipettes database providing you with pipette r elated data, parameters,
tested volume, and errors values determined for specific volumes.
Prior pipette calibration process load the pipettes database with data on pipettes and calibration
criteria. In order to add pipette it is necessary to enter the database f irst. For information on how to
add pipette to pipettes database read down this user manual.

24.5. PIPETTES CALIBRATION START-UP
In order to carry out pipettes calibration process you need a special adapter which is non-standard
balance equipment. The adapter facilitates calibration process and/or piston pipettes check and it is
intended for 3Y and 4Y balances.
The adapter has been designed to minimize evaporation occurring in t he course of weighing liquids.
It comprises a mini weighing chamber installed inside the weighing chamber of a balance, an
evaporation ring and a dedicated weighing pan enabling to locate a measuring vessel in the very
centre.
Application of the adapter prevents r is k of liquid evaporation during the calibration process. Compact
dimensions of the adapter along with use of the evaporation ring enable maintaining high humidity
rate inside the weighing chamber.
Carried out research has proved that the adapter eliminates or considerably reduces liquid
evaporation process. Eliminated/reduced liquid evaporation is a key factor while calibrating piston
pipettes by means of a gravimetric method.
Selecting an appropriate adapter and balance mostly depends on calibrated pipettes type.
Prior pipettes calibration start install the adapter inside the weighing chamber, next enter data
relating to pipettes that are to be calibrated, include complet e pipette characteristics and values of
errors (see: Database of Pipettes).
Now set pipettes calibration parameters:
• Measurements quantity
• Request serial number (YES/NO)
• Operation with adherence to ISO 8655 (YES/NO)
• Upload ambient conditions parameters from THB module (YES/NO)

25. DIFFERE NTIAL WEIGHING
< Differential weighing> is a working mode enabling you to analyse changes of mass of
a single sample or multiple samples.
The process is carried out by determining sample’s initial mass, next the sample is subjected to
different processes, as a result some sample’s ingredients are either separated or added. Finally, the
sample is repeatedly weighed (differential weighing). After the f inal weighing, the balance deter mines
the difference between the two mass values (initial and final).
Differential weighing mode enables you to:
• Determine a series, where each series may contain several samples
• Ass ig n a name for each series, print or export data on a series to a connected USB flash drive;
• For each sample: determine tare value, initial mass and carry out up to five measurements for
the final mass.
In order to operate differential weighing mode, first it is necessary to enter weighing series to the
database, define samples in the series, next trigger the series. To create series go to series
database. For more information on how to create series read further down this user manual.

26. STATISTICAL QUALITY CONTROL - SQC
< Statistical Quality Control> is a working mode enabling support control of product packing
process.
It enables detecting surplus or shortfall of product in a packaging.
If the weighing results are stored in the database, then trend analysis can be carried out and
displayed in a form of a chart.
The software provides the possibility of controlling a batch comprising up to 1000 samples.
Each completed control process is saved to the SQC database, and its results are ready for
previewing in an optional moment. Each series has a determined set of parameters that are stored in
the database: maximum, minimum, standard deviation and average value for each batch, etc.
SQC control process can be carried out manually (by pressing <PRINT> button for each
measurement) or automatically (automatically carried out record of stable measurements).
The balances feature module for statistical control processes. It is supported by a database
containing list of products with error values (<T2->, <T1->, <T1+>, <T2+>) declared for each product.
The control process is initiated automatically and completed on controlling a required quantity of
samples. As a user you define how many samples are to be controlled, to do it go to SQC settings.
After completed control process a final report can be generated and/or printed. Data on a control is
also automatically saved to the Database of SQC Reports.
Control process:
• User s elect ion,
• Pr oduc t selection,
• Cont r ol start,
• Acquiring weighing records,
• Control finish (carried out automatically when predefined number of samples is weighed -
batch),
• Cont r ol r eport print.
