9.6. Use of air buoyancy correction factor

AET_/PET_/ILT_NM-BA-e-1410 25

Sample mass [g]

The application enables correcting mass measurement errors during:

1. Weighing loads that density considerably differs from the density of
standard used to adjusting the balance. Regularly, 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 should apply.

Below chart presents the value of mass correction in relation to the density
of weighed load, assuming that air density is constant and equals

1.2 kg/m3.

Correction value [mg]

Density of weighed load

Error value in relation to density of weighed sample

2. Testing the changes of sample mass within a few hours’ time, if: sample
mass is relatively constant (minor changes). In such case it is assumed,
that considerable effect on the measurement result rests on air density
changes, which is affected by changes of pressure, temperature and
humidity.

In order to carry out a reliable measurement, apart from being familiar with
relations applying to ambient conditions, an operator should know the measuring
methods, features of tested sample, air density in the laboratory room and
density of weighed sample.

FUNCTIONING

The application provides two ways to use the air buoyancy correction procedure.

26 AET_/PET_/ILT_NM-BA-e-1410

1. Inserting the specified value of air density and specified value of weighed
sample density to balance’s memory.

On inserting these values the application automatically calculates the
correction factor for weighed mass and indicates corrected value of
weighed mass on balance’s display.

In order to avoid errors, the corrected mass value is accompanied by <!>
symbol visible on balance’s display and a printout.

2. The application semi-automatically determines the value of air density. The
specified density of the weighed sample is inserted to balance’s memory by
an operator.

Determination of air density is carried out using a set of two mass
standards. One of them is made of stainless steel, and the other of
aluminum. Based on mass indications of the two standards, the software
automatically calculated the air density and saves the value in balance’s
memory on operator’s confirmation. Then the density of weighed sample
has to be inserted to balance’s memory.

On inserting these values the application automatically calculates the
correction factor for weighed mass and indicates corrected value of
weighed mass on balance’s display.

As in case 1, the corrected mass value is accompanied by <!> symbol
visible on balance’s display and a printout.

Air buoyancy correction mode is enabled / disabled from the level of user menu.
The application is operating in weighing mode only.

STARTUP AND OPERATION OF AIR BUOYANCY CORRECTION
PROCEDURE

• While in main window press grey coloured workspace

• Select option <Settings>

• Select parameter < Air buoyancy correct ion>

Accessible settings

- Air buoyancy correction – YES/NO

- Sample density (insert the density value of weighed sample). If an
operator uses products from databases, then on product selection
its density value is automatically uploaded.

- Air density – for selecting the means of inserting the air density
value used for calculating buoyancy correction factor.

AET_/PET_/ILT_NM-BA-e-1410 27

Settings:

VALUE – selecting this option opens a window for inserting
determined value of air density (e.g.: determined using other
methods). The inserted value is used to calculating buoyancy
compensation factor. The value is assigned automatically on
carrying out the air density determination (on its completion by

pressing < > key).
ONLINE – selecting this option downloads current air density value

from a connected THB sensor, if such is connected to the balance,
or from internal sensor installed in the balance.
If a balance features both types of sensors (THB module and
internal sensor), then data from the THB module supersedes the
other, and parameters Setup/Ambient Conditions/Ambient
Conditions Module require setting to SAVE or SAVE & ALERTS
mode.
If a balance features only one type of the sensors for temperature,
humidity and pressure recording, then correct ONLINE operati on
requires setting of balance parameters:

− Internal sensors only - Setup/Ambient Conditions/Ambient
Conditions Module set to NONE,

− External THB module only - Setup/Ambient
Conditions/Ambient Conditions Module set to SAVE or

SAVE & ALERTS mode.

Additionally, for correct balance cooperation with the THB mod ule
set port’s transmission parameters to compatible with those of the
THB 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 below drawing. 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 an
operator inserts to balance’s memory the actual value on the air density and
correct density of weighed sample.

28 AET_/PET_/ILT_NM-BA-e-1410

Caution:

If the <AIR BUOYANCY CORRECTION> mod e is set to <ONLINE> value, then
balance display does not indicate pictogram <!> which means that parameter
Setup/Ambient Conditions/Ambient Conditions Module is set to SAVE
or SAVE & ALERTS mode, and there is no physical connection between a
balance and a THB module, or the parameters for communicating the module
with the balance are set incorrectly. In such case plug a THB module to
balance’s ports COM 1 or COM 2 and set appropriate cooperation parameters,
such as specified on module’s data plate.

compared to each other in constant time intervals. If the results differ
less than declared AUTOZERO range, e.g. 1 division, the balance is
automatically zeroed, and the markers of stable indication and
precise zero are displayed.
Active AUTOZERO means, that each measurement starts from the precise
zero point. There are, however, cases where the function may disturb the
weighing process. For instance during very slow load placing or pouring
onto the balance’s weighing pan. In such case, the correcting system of
zero indication may also correct the actual indication of a load placed on
the weighing pan.

14. WORKING MODES – general information

A balance in its standard version features the following working modes:

Weighing
Means of operation: weight of a load is determined through an
indirect measurement. A balance measures gravitational force
which attracts the load. An obtained result is processed to a
digital format and displayed in a form of measurement result.

Parts counting
Means of operation: based on a determined mass of a single
part it is possible to count another parts, assuming that mass
of a single part is determined with sufficient accuracy, and that
the following parts are equal in mass.

Checkweighing

Means of operation: control of sample mass with applied
thresholds. A user should specify the value of low threshold
<LO> and high threshold <HI>.

Dosing

Means of operation: a user should specify sample’s target
mass to be obtained by pouring.

Means of operation: control of percent ratio of a sample in
relation to a standard (reference). Obtained data provides
percent ratio on how test sample differs from the accepted

Density

Means of operation: based on Archimedes principle, a balance
determines density of solids and liquids. The mode requires an
optional density determination kit.

Animal weighing

Means of operation: mass measurement takes place with
application of filters dampening animal moves on a weighing
pan, thus enabling obtaining a correct measurement result.

Means of operation: by adding a sequence of ingredients, a
user can prepare an optional mixture or formulation. Before
mixing balance software requires designing a formulation by

Statistics

Means of operation: carried out measurements are used to
calculate statistical data, such as Min, Max, deviation, etc.

Statistical Quality Control

(mode not available in balance’s standard version)

Means of operation: calibration of pipettes according to
procedures listed in ISO 8655 or according to user

Differential weighing

Means of operation: analysis of mass sample change over
time.

Working mode is intended to carrying out different types of
product packing processes and aimed at monitoring and / or
controlling the packing process. It enables detecting excess or
lack of product quantity in a packaging.

21. FORMULATION

Working mode < Formulation> enables preparing mixtures out of several
ingredients. The process is conducted automatically.
Balance user, while preparing mixtures, can:

 use database of formulas, where formula records are stored. In such

case, balance’s software assists in weighing ingredients of a mixture by
displaying corresponding commands or information in the grey colou red
workspace;

 prepare a mixture without using database of formulas. Then, a user

controls weighing of an ingredient, weighing sequence and quantity.

Should database of formulas be used, first a formulation has to be created in the
database, and then it is recalled (activated) for use. Creating a formulation is
carried out only from the level of Database of Formulas, and it is described later
in this section.

Working mode activating procedure

• while in the main window, press soft key located in the upper bar of the

display, which opens a submenu <Working modes> with selection of
available working modes,

• select < Formulation> mode, the software automatically returns to the

main window and displays pictogram in the upper bar.

− Automatic ingredients’ naming:

o YES
o NO

− Apply tare from database of tare values:

o YES, each of used ingredients has a tare value assigned in

accordance with a product saved in the database of products;

o NO, tare is not applied

− Means of verifying an ingredient:
The option enables selecting a relation used for determining correct
mass of ingredients during formula making process.
TOLERANCE/TOLERANCE THRESHOLDS: balance software accepts

AET_/PET_/ILT_NM-BA-e-1410 83

mass of an ingredient if it is within set percent tolerance of total
ingredient’s mass (±%) - (data acquired from database of products).
THRESHOLDS: the software accepts mass of an ingredient as correct if
it is within set thresholds (data acquired from database of products).

Selected relation is in effect for all ingredients in the formula making
process.

− Multiplier editing, enables making multiple mixtures according to a

selected formulation in a single weighing process:

o YES, on selecting a formulation for processing, the software

requests for specifying multiplier’s value used for multiplying mass
of each ingredient while weighing. Inserted value is in effect for all
ingredients in the formula making process.

o NO, inserting multiplier value is disabled, default value is set to

<1>

− Printout, means of using the function is given in point 10.8. “Additional

21.2. Formulation – quick access keys

Each of working modes features a set of default quick access keys which are
automatically displayed on mode activation. The set of keys can be modified
by selecting other quick access keys to the bottom bar of the display. Such
process requires appropriate operator’s access level.

21.3. Adding formulas to the Database of Formulas

Database of formulas consists of formulas names, and ingredients with names
and mass forming a formulation. Each product used for formula making
process is saved in the database of products. When preparing a formulation,
the first step requires naming the formulation, and then adding ingredient’s to
already named formulation.
The software operates intuitively, and commands a user to follow displayed
information.

As each of ingredients must have its name and mass specified, the operator
must know the exact composition of the total mixture. Adding a formulation to
the database of formulas is carried out from the database level.

84 AET_/PET_/ILT_NM-BA-e-1410

Procedure:

• Enter submenu < Databases>, press < Formulation> field

• Press < Add > soft key, should a formulation be added

• Press:

ingredients used in a formulation (in case of a new formulation, the list
of ingredients is empty), add new ingredients to a formulation:

• Press < Add > soft key

• Select one of available options:

<New ingredient> - adding a product, which is absent in the database
of products. On selecting this option, first insert a name of a new
product, then specify its mass to be weighed during formula making
process. The software automatically adds the products to the database of
products.

Caution: after adding the product, balance user can fill in other data on a
product from the database level.

<New ingredient from database> - on selecting this option, a window
with the Database of Products is opened. Using displayed list select a
product to be weighed in the mixture, mass to be weighed is the mass of
the product saved in its record in the database.

The value of mass of each added product is editable. Changing mass of
an ingredient in a formula does not immediately change product’s mass
saved in the database.

4. Number of ingredients – non-editable option, it is updated by the
software on adding the following ingredient to a formulation.

5. Sum – target mass of a formulation, i.e. sum of all ingredients in a
formulation. It is not editable, and it is updated by the software on
adding the following ingredient to a formulation.

AET_/PET_/ILT_NM-BA-e-1410 85

21.4. Using formulas in weighing

In activating FORMULATION mode, depending on settings, user can move to
formula making process either on selecting a formulation from corresponding
database or weigh a mixture “manually”.
Preparing mixtures is carried out by:

− Preparing a formulation that is not saved in the Database of Formulas –
i.e. “manually”,

− Preparing a formulation that is saved in the Database of Formulas,

− Preparing multiple repetitions of a formulation that is saved in the

Database of Formulas – multiplier function,

− Preparing a formulation that is saved in the Database of Formulas, with
determining target mass of complete formulation.

Caution:

23. PIPETTE CALIBRATION

Working mode < Pipette calibration> is dedicated to determining
measurement errors of volume in piston pipettes, in accordance with standard
ISO 8655 or according to user requirements.
In case of calibration carried out in accordance with standard ISO 8655, the
errors are auto matically selected to te sted volume, as specified in the standard
(see table of errors for standard ISO 8655).

Working mode enables:

• Calibrating pipettes with fixed or adjustable volume, single or multi-
channel;

• Preparing a database of pipettes including: pipette name, code, tested
volume and others;

• Calculating results on basis of:

Average volume of a pipette (channel)
Systematic error es (accu racy error)
Random error CV (repeatability error)

• Carrying out automated measuring procedures with consideration of
pipette’s type;

• Storing calibration results in a database (in a form of reports from
calibration process);

• Printing reports from pipette calibration process

• Exporting reports from tests

During volume testing procedure, the software determines accuracy and
repeatability errors f or tested volume.
In case of pipettes with adjustable volume, the softwar e enables dec laring up to
5 volume from total pipette’s range, that are checked during calibration process.

In order to ensure the highest accurac y of pipettes calibration process,
maintain the following ambient conditions at a workstation:

 Ambient temperature of a pipette, tips and liquid shoul d be kept between

20°C - 25°C with change rate during testing within ± 0.5°C

 Relative humidity 50 - 75%

and

 Use distilled water for pipettes calibration processes
 A pipette, tips and distilled water should be stabilized for temperature in

the weighing room. The reference norm advises that minimum
acclimatization time for above mentioned is 2 hours.

While calibrating process, balance user refers to the database of pipettes
including data on pipettes, its parameters, tested volume, and values of errors
determined for specific volumes.

Before carrying out calibration process, load database with data on pipettes and
calibration criteria.

requirements. To access the setting follow below procedure:

Procedure:

1. Press grey coloured workspace,

2. The display indicate s menu of: Settings, Keys, Information, Pr intout
and Profile,

3. Press <Settings> key,

4. The display indicates functions related to calibration of pipettes.

Pipettes calibration is related to the following functions:

− Number of measurements; this opt ion enables determining number o f
measurements for tested volume of a pipette (valid for each tested
volume in case of a pipette with adjustable volume),

− Request serial number: YES/NO. For option <YES> before starting
calibration procedure, the software displays a window and on-screen
keyboard for inserting serial number of a pipette,

− Comply with ISO 8655: YES/NO. For option <YES>, for tested
volumes, during pipettes calibration process the software automatically
accepts error values as specified in standard ISO 8655 (if other error
values have been accepted for a pipette, then on selecting option
<Comply with ISO 8655> the error values are negle cted, and r eplaced by
those from ISO standard),

− Acquire data on ambient conditions from THB mod ule: YES/NO. For
option <YES> the software automatically, and in specified moment,
acquires and saves ambient conditions’ parameters fro m a connected T HB
module. If option < NO> is selected, befor e starting and after co mpleting
the pipettes calibra tion process operator should manually insert ambient
conditions parameters (i.e. temperature, humidity and pressure in the
weighing room) from external ambient conditions sensors.

− Result control, Tare mode, Automatic footer printout, Printout

mode, Printout, means of using these functions is given in point 10.8.

23.2. Pipettes calibration – quick access keys

Each of working modes features a set of defaul t quick access keys which are
automatically displayed on mode activation. The set of keys can be modified
by selecting other quick access keys to the bottom bar of the display. Such
process requires appropriate operator’s access level.

23.3. Adding a pipette to the Database of Pipettes

Database of pipettes contains list of pipe ttes’ names and other da ta including
tested volume and err ors values for a specific volume. Whe n adding a pipette
to the database, first specify its name, and then add other data on a pipette.
The software operates intuitively, and commands a user to follow displayed
information.

Adding a pipette to the Database can be carried out in menu of the database.

Procedure:

• Enter submenu < Databases>, press < Pipettes> field

• Press < Add > soft key, should a new pipette be added

The software automatically adds a new entry to the database, and enters its
editing mode. Insert all parameters of a new formulation.

List of parameters defined for a pipette:

1. Name: press “Name” field, a window opens for inserting name of a
pipette;

2. Code: for inserting pipette’s code;

3. Model: for inserting model name of a pipette;

4. Tip: for inserting name of used tip;

5. Type of volume: ADJUSTABLE / FIXED;

6. Nominal volume: for specifying nominal volume of a pipette;

7. Mini mum volume: for specifying the minimum volu me of a pipette (in
case of a pipette with fixed volume, insert <0>);

8. Number of channels: for specifying number of pipette’s channels, in
case of a single channel pipette insert <1>;

9. Type: NONE/A/D1/D2. Pipette type is compatible with applicable
standard. Selecting pipette’s type is mandatory if calibration process
complies with the requirements of standard ISO 8655, as values of
errors differ in each type of a pipette. Therefore, if the software is to
accept adequate error values it is necessary to determine type of a
pipette;

10. Tested volumes: if pressed, a window is opened with a list of
calibrated volumes (in case of a new pipette, the list is empty), add
volume to be tested, and define error value for each tes ted volume:

• Press < Add > soft key

• A window with on-screen numeric keyboard is displayed,

• Insert value of tested volume in [µl] and accept by pressing <

> key,

• A new record is automatically added to the list with recommended
error values,

• In order to change error values press a field with added volume
of a pipette,

23.5. Working mode activating procedure

Carrying out pipettes calibration process requires installing an adapter for
pipettes calibration. The adapter does not come standard with the balance.
The adapter for pip ettes calibration is a simple supplementary device dedicated
for calibration and che cking of p iston pipette s. The adapter has be en des igned to
minimize evaporation occurring in liquid handling procedures. It consists of a
minimized weighing cha mber installe d inside the w eighing chambe r of a balance.
The adapter features an evaporation ring and a dedicated weighing pan for
central locating of the measuring vessel.
Application of the adapter for pipettes calibration prevents from liquid
evaporation during calibration process. Small dimensions of the adapter,
combined with the evapora tion ring enable maintain ing high humidi ty rate inside
the weighing chamber and the measuring vessel, thus stopping liquid
evaporation process.
Carried out research proved that the adapter for pipettes calibration eliminates
or considerably reduces liquid evaporation process, which is essential for correct
gravimetric calibration of piston pipettes.
Selecting an appropriate adapter and balance mostly depends on type of
calibrated pipettes.
Before starting pipettes calibration process, assembly the adapter inside
balance’s weighing chamber, and insert data on pipettes to be calibrated,
including complete pipette characteristi cs and values of er rors (see: Database of
Pipettes).

The following step is setting process’s main option:

• Number of measurements

• Request batch number (YES/NO)

• Operation with ISO 8655 (YES/NO)

• Acquire ambient conditions from THB module (YES/NO)

Caution:
Description of options and settings are given in point 24.1 of this user manual.

After setting the above options, go to pipettes calibration process.
