3.4. Maintenance Activities
Electric shock.
Some balance models are equipped with an ionizer. Make sure to take special
safety measures during maintenance.
1. The balance must be disconnected from the mains before maintenance. 2.
Ensure that no liquid comes into contact with the power supply. 3. Never open
the balance housing, terminal, ionizer or power supply they contain no
internal components that can be cleaned, repaired or replaced by the user. 4.
Do not connect the balance to the mains until the cleaned parts are dry. 5.
Any maintenance activities or cleaning must be performed 5 minutes after
disconnection of the device from the mains. 6. The emitter pins are sharp. Do
not touch them directly as this may cause body injury.
The ionizer covers have to be cleaned at least once a month using a lint-free
cloth soaked with alcohol-based substance.
CAUTION: Cleaning the weighing pan while still installed may cause damage
of the measuring system.
1. Uninstall the weighing pan and other detachable components (the components
differ depending on a balance type see section: UNPACKING AND INSTALLATION).
Be careful while installing the components so as not to cause any damage to
the balance mechanism. Remove the weighing pan of a microbalance using
tweezers.
2. Using handheld vacuum cleaner remove dust from the weighing chamber
(recommended for the microbalance).
3. In order to ease cleaning of some of the weighing instrument components,
it is permissible to remove them following the below instruction.
Cleaning anti-draft chamber panes:
Select dissolvent depending on the type of contamination. Never soak the glass
panes in alkaline solutions since they interact with glass and may cause
damage. Do not use cleansers containing 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 protophilic solvent (sodium carbonate), to remove BASE use
protogenic solvent (mineral acid of various concentration).
– 22 –
In case of heavy contamination, use brush and detergent, nevertheless avoid detergents containing large and hard molecules which could potentially scratch glass panes.
At the end of the cleaning process rinse the pane using distilled water.
Use soft brush with wooden or plastic handle exclusively to avoid risk of scratches. Do not use wire brush.
Rinsing is a necessary cleaning process stage allowing to remove remaining soap, detergents and other cleansers from the panes prior to their reinstallation.
After the preliminary cleaning process stage, rinse the pane using running water first, distilled next.
Avoid drying the panes either using paper towel or forced air circulation since some fibres, grains or contamination of other type could permeate into the panes thus causing weighing errors.
We do not recommend using 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 process stage you need running water or wet sponge with large pores, this will help you to remove loose, heavy dirt.
Do not use cleansers containing abrasive substances.
Next, using cloth and cleanser-water solution (soap, dishwashing liquid) gently rub the surface.
Avoid using cleanser without water since it may result in 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 cleansers containing 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 to make the surface shine.
Cleaning stainless steel components When cleaning stainless steel components, the following table should be followed, which lists the types of contamination and ways of removing it.

buttons marked with arrows to
release chamber for filter weighing (3) and remove it.
CAUTION: Pay special attention while assembling the chamber. Guide the pins so
that they are evenly inserted into the base openings (inaccurate inserting of
the pins will cause incorrect assembly and may cause balance damage).
Disassembly steps for XA 5Y.A, XA 5Y:
Remove the weighing pan and the draft shield. Clean the components when detached. With this, your balance mechanism is protected against accidental damage.
Undo and remove the top pane protection, next slide the pane out of a guide bar.
– 25 –
Remove the left and the right side pane. Before removing the panes completely, pull away the protection, see the picture on the left. The side panes are not interchangeable, therefore, remember which is left and which is right. Upon cleaning procedure completion, the panes must be installed on the correct sides.
Undo and remove the top frame protection, next disassembly the top frame.
Remove the front pane.
Clean the weighing chamber and the panes. All the operations have to be done
carefully. Pay special attention to the spot where the weighing pan is
installed; dirt and other small elements may enter the balance construction
through this opening. This may cause incorrect operation of the instrument.
Upon maintenance is completed, carry out the same set of actions in a reverse
order. Pay special attention to the left and right side panes, assembly them
on the correct side of the balance. While sliding the pane back onto its
place, remember to pull away the protection (like before, when disassembling
the anti-draft chamber).
3.5. Connecting the Balance to the Mains
The weighing device can be connected to the mains only with a power supply
that comes standard with the particular model. Nominal voltage of the power
supply (specified on the power supply data plate) has to be compatible with
the mains nominal voltage. Plug the balance to the mains connect the power
adapter to the socket, next connect its connector to the interface located at
the back of the balance housing.
3.6. Temperature Stabilization Time
Prior to the measuring processes start, it is necessary to wait until the
balance reaches thermal stabilisation. Balances stored in much lower
temperatures, than the workroom temperature, before being plugged to the mains
must be subjected to thermal stabilisation. The thermal stabilisation period
takes about 12 hours. During the thermal stabilization, the indications on the
screen can change. Potential workroom temperature change shall be
insignificant and occur slowly. Thermal stabilization also applies to the
monitoring system and automatic balance levelling.
3.7. Connecting Peripheral Equipment
Use only accessories and peripheral equipment recommended by the manufacturer.
The balance must be unplugged from the mains before connecting or
disconnecting any peripheral equipment (printer, PC, computer keyboard of USB
type or extra display). Upon connecting the peripherals, plug the balance to
the mains.
– 26 –
3.8. Balances with Integrated Ionizer
Safety notes contain important information on safety issues. Ignoring the
safety notes may lead to personal injury, damage to the instrument or
breakdown. Safety notes are marked with the following signal words and warning
symbols:
Do not touch ions source. This may cause electric shock (during operation) or
injury (components generating ions are sharp). Should you notice any signs of
incorrect operation (smoke, burnt material smell, irregular ionizer warming),
disconnect the device from the power supply immediately. Should water or any
foreign bodies get inside the ionizer, behave likewise, i.e. disconnect the
ionizer from the mains immediately.
Due to high voltage, typical for the ionizer, remain extremely careful while
operating it.
It is not allowed to either disassemble or modify the ionizer. Use the device
only as intended.
The antistatic ionizer, a built-in component of the XA 5Y.M.A.I microbalance
and the XA.5Y.A.I balance, neutralizes electric charges inside the weighing
chamber upon placing the sample in it. The lower the value of relative
humidity and a reading unit of the balance, the more evident influence of
static electricity. The ionizer neutralises any uncompensated electric charge
accumulated on the weighed object. Affected operation results in greater
repeatability error, often also greater error of indication. Measurement
errors, due to the harmful effects of electrostatics, often reach the value of
thousands of reading units and more. The problem concerns non-conductive
samples, e.g. glass flasks, paper filters, plastics, etc. Implemented in the
XA 5Y.M.A.I microbalance, the antistatic ionizer is a modern technology
solution which compensates both cations and anions. The ionizer activates when
the balance door opens, and deactivates when the door is closed. It is
possible to control the ionizer using quick access button.
Press to start/stop ionizer operation.
Press to activate.
Press to deactivate.
The operation is signalled by blue LED diode (installed at the back of the
weighing chamber) which emits light when the ionizer is on.

General Information 5Y series balances feature the following working modes:
Weighing Means of operation: weight of a load is determined through an
indirect measurement. The balance measures gravitational force which attracts
the load. The obtained result is processed and displayed on the balance screen
in a digital format. Checkweighing Means of operation: control of sample’s
mass carried out with reference to specified thresholds, it is necessary to
give the value of min threshold .
Parts counting Means of operation: based on a weight value of a single piece,
it is possible to count pieces quantity; necessary conditions: the weight
value of a single piece is determined with sufficient accuracy, the mass of
all the pieces is the same.
Dosing Means of operation: it is necessary to specify sample’s target mass to
be obtained by dispensing (pouring, filling, etc.).
– 50 –
Percent weighing Means of operation: control of percent ratio of a test sample in relation to a reference sample. Obtained data provides info on how much the test sample differs from the adopted reference sample. Animal weighing Means of operation: mass measurement carried out with use of filters which dampen animal moves on a weighing pan; the filters enable obtaining correct measurement result. Statistics Means of operation: carried out measurements are used to calculate statistical data such as Min, Max, deviation, etc.
Density Means of operation: based on Archimedes principle, it is possible to
determine density of solids and liquids. Density mode requires use of an
optional density determination kit.

NO
NO
Place weighed loads centrally on the weighing pan.
Avoid side loading, in particular side shocks.
Prior to weighing or in the case of ambient conditions change, it is necessary to carry out balance adjustment.
· Prior to the measurement, it is recommended to load the weighing pan several
times with mass close to the maximum capacity. In the case of instruments
offering two reading units (d), the initial load of the weighing pan depends
on the reading unit value. Example: For the XA 82/220.5Y balances with d1=
0.01mg and d2=0.1mg, load the weighing pan as follows: 50 g weight for
measurements with d1=0.01mg and 200 g weight for measurements with d2=0.1mg.

Use of Air Buoyancy Compensation Factor
The application enables correcting mass measurement errors in the course of:
- weighing loads of density considerably different from the density of a standard that has been used to adjust the balance. Typically, the balance is adjusted with a steel mass standard of ~8.0g/cm3 density or a brass mass standard of ~8.7g/cm3 density. If loads made of other substances are weighed, then ratio indicated on below graph applies;
Error value versus density of weighed sample
The graph presents correction values for mass depending on the density of weighed load, assuming the air density to be a constant value of 1.2 kg/m3..
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 the final result considerably, wherein
the density is influenced by changes of pressure, temperature and humidity.
For measurements to be reliable, the density of the air in the laboratory and
the density of the material to be weighed must be determined (depending on the
ambient conditions, the measurement method and the properties of the material
under test).
– 61 –
FUNCTIONING The air buoyancy compensation procedure is to be used as follows:
1. Method 1: Enter air density value and the density value of the weighed
sample to the balance memory. Wait, the software automatically calculates the
correction factor for weighed mass. Next, the corrected value of weighed mass
is displayed. To avoid mistakes, the <!> symbol is presented next to the
corrected mass value (on a display and a printout).
2. Method 2: Determine air density value using the balance program (semi-
automatic operation) and enter the value of the weighed sample density to the
balance 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 aluminium.
Based on mass indications of the two standards, the program automatically
calculates the air density and saves the value in the balance memory on
operator’s confirmation. Now, enter the density value of the weighed sample to
the balance memory. Wait, the software automatically calculates the correction
factor for weighed mass. Next, the corrected value of weighed mass is
displayed. To avoid mistakes, the <!> symbol is presented next to the
corrected mass value (on a display and a printout).
In order to enable/disable the air buoyancy compensation procedure, go to the
user menu. The procedure only works in the weighing mode.
AIR BUOYANCY COMPENSATION START-UP
Procedure: · Enter home screen and press grey workspace. · Select
Parameter values: VALUE select to open a window to enter a specified air density value (e.g.: determined by means of other methods). The entered value is used in the course of compensation. It is assigned automatically upon completed air density determination (to complete air density
determination, press <
button).
ONLINE select to make the balance acquire air density value from a connected THB
sensor at a real time, if such is connected to the balance, or from an internal sensor installed
in the balance.
If your balance features both types of sensors (THB and internal), then data from the THB
supersedes the other. In such a case, go to Setup/Ambient conditions/Ambient
conditions module parameter and set SAVE or SAVE & ALERTS value.
If your balance features only one set of sensors recording temperature, humidity and
pressure, then correct ONLINE operation requires setting the following parameters:
– internal sensors exclusively go to Setup/Ambient conditions/Ambient conditions
module parameter and set NONE value,
– 62 –
– external THB sensor exclusively go to Setup/Ambient conditions/Ambient
conditions module parameter and set SAVE or SAVE & ALERTS value. For correct
balance cooperation with the THB sensor, it is necessary to set port’s
transmission parameters. They must be compatible with those of the THB sensor.
The THB sensor’s transmission parameters are detailed on its data plate.

14.7. Cooperation with Titrators
In order to provide correct cooperation with TITRATORS, go to standard
printout content settings and set
Usually the vibrations are dampened with use of anti-vibration tables. A
signalling device, i.e. ambient conditions module equipped with a vibration
sensor, is used to support the process of vibrations dampening. Such device
comes standard with each 5Y 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 5Y series balance in real time. In the case of
the module that is an integrated part of the balances manufactured by RADWAG,
the filters analyse those frequencies to which the weighing devices are
sensitive. In the case of balances, effective value (rms value) measured from
3 axes and for a particular time interval is given, such value provides
information on amplitude and history of disturbances. Radwag has designed an
analysis method and selected permissible vibration thresholds respectively to
make signalling device operation both effective and convenient (not
troublesome). Balance screen displays balance-registered vibration level in
percent. Vibration 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:
– 68 –
For better understanding, analyse the following example (the values used below
are exemplary ones, they were not taken from the balance). 1. Assumed
vibration threshold set by default on 5Y series balance: 100 mm/s2. 2. Max
vibrations value: 100% (threshold for alert pictogram colour change, from
green to
red). Pictogram colour is green for vibrations within 0 100 mm/s2 range, for
vibrations value of 101 mm/s2, the pictogram changes to red. 3. Max vibrations
value: 150%. Pictogram colour is green for vibrations within 0 – 150 mm/s2
range, for vibrations value of 151 mm/s2, the pictogram changes to red.
Vibrations are signalled by a respective pictogram displayed in the weighing
result window. A window with the current sensor values is presented in the
middle of the display on the right. Displayed vibration value (Vibrations) is
the effective value registered within the most recent 2 seconds. This value is
refreshed every 2 seconds. If the screen displays 100%, this means that
vibrations have reached the threshold set by RADWAG.
Vibrations are recorded in the database, this allows to analyse the history of
ambient conditions quality.
– 69 –
The 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.
By default, the interval is set to 10 min; this value may range between 1 – 60
min. Record analysis allows the user to select the optimal time of the day for
the measurements to be carried out, i.e. the time when the ambient 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 vibration that occurred in the
course of the measurement are saved.
