5 WORKING MODES- GENERAL INFORMATION
The balances feature the following working modes:
Weighing
The weight of a load is determined through an indirect measurement. A balance measures gravitational force that attracts the load. The result is processed to a digital format and displayed in a form of measurement result.
Parts counting
Based on a determined mass of a single part, it is possible to count several parts, assuming that the mass of a single part is determined with sufficient accuracy and that the following parts are equal in mass.
Checkweighing
Control of sample mass with applied thresholds. The user specifies the value of low threshold (LO) and high threshold (HI).
Dosing
The user specifies the sample’s target mass to be obtained by
pouring.
Percent Weighing
Control of percent ratio of a sample in relation to a reference standard. Obtained data provides a percent ratio on how the test sample differs from the accepted standard.
Density
Based on Archimedes principle, a balance determines density of solids and liquids. This mode requires the optional density determination kit.
Animal Weighing
Mass measurement takes place by using filters that dampen animal moves on a weighing pan, thus enabling obtaining a correct measurement result.
Formulation
By adding a sequence of ingredients, a user can prepare a mixture or formulation. Before mixing, the balance’s software requires designing a formulation by specifying its ingredients and their mass.
Statistics
Completed measurements are used to calculate statistical data, such as Min, Max, deviation, etc.
Page 25
25
Pipette calibration
Calibration of pipettes according to procedures listed in ISO 8655 or according to user requirements.
Differential Weighing
Analysis of a mass sample’s change over time.

13.1 ADDITIONAL SETTINGS
The additional settings enable users to adjust the working mode to their needs. To access the setting follow the below procedure:
Touch the gray workspace area.  The menu shows: Settings, Keys, Information, Printout, and Profile.  Press the <Settings> key.  The display shows functions related to formula making process.
The formula making process is related to the following functions:
Automatic ingredients’ naming:
YES  NO
Apply tare from database of tare values:
YES, each of the ingredients used has a tare value assigned to a product that is
saved in the database of products
NO, tare is not applied
Means of ingredient verification:
The option enables the user to choose a ratio for determining the correct mass of
ingredients during the formula making process.
TOLERANCE/THRESHOLDS
TOLERANCE: The balance software accepts the mass of an ingredient if it is within
set percent tolerance of the total ingredient’s mass (±%) (data acquired from
database of products).
THRESHOLDS: The software accepts the mass of an ingredient as correct if it is
within set thresholds (data acquired from database of products).
The selected ratio will be in effect for all ingredients in the formula making process. If during formula making process one ingredient’s mass is exceeded (not within the set
percent tolerance and above its upper set point in relation to its target mass), upon
confirmation of ingredient mass, the message “Value out of range, recalculate the
formulation?” will appear. Upon confirmation, the software will automatically recalculate
the mass of other ingredients so that mixture proportions are correct.
This option is available when the ingredients’ saved data in the database comply with the selected option “Means of Ingredient Verification.” This means an ingredient is specified with thresholds, and the “Thresholds” value is selected for the “Means of Ingredient Verification” option. If the data don’t agree, automatic recalculation is not
available. That is, if thresholds are entered for the ingredient where “Means of Ingredient Verification” is set to the value “Tolerance.”
Page 52
52
Multiplier’s editing: This allows the user to make multiple mixtures according to a selected formulation in a single weighing process:
YES: On selecting a formulation for processing, the software requests to specify the
multiplier’s value to be used for multiplying the mass of each ingredient while
weighing. The value entered will be in effect for all ingredients in the formula making process.
NO: Entering the multiplier value is disabled, and the default value is set to 1.
13.2 ADDING FORMULAS TO THE DATABASE OF FORMULAS
The database of formulas consists of formulas’ names and ingredients, with names and mass
forming a formulation. Each product used for the formula making process is saved in the database of products. When preparing a formulation, the first step requires naming the
formulation and then adding ingredients to an already named formulation. The software operates intuitively and gives the user commands to follow on the display.
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 performed at the database level.
Procedure:
Enter the “ Databases” submenu and press <Formulation>.
Press the < Add> soft key to add a formulation.
The software will automatically add a new entry in the database and enter its editing mode. Enter all the parameters for the new formulation.
List of parameters defined for a formulation:
Press <Name> and enter a name for the formulation.  Enter the formulation code.  Press <Ingredients>, and a new screen opens with a list of ingredients used in the
formulation (for a new formulation, the list of ingredients is empty).
Press the Add> soft key to add new ingredients.  Select one of available options:
– New ingredient - Add a product not yet in the database of products. First,
enter the name of the new product, then specify its mass to be weighed during the formula making process. The software automatically adds the products to the database of products.
Hint: After adding the product, the balance user can fill in other data on a product from the database level.
– New ingredient from database - Opens the database of products screen.
From the list, select a product to be weighed in the mixture. The mass to be weighed is the mass of the product saved in its record in the database. The value of the mass of each added product is editable. Changing the mass of
Page 53
53
an ingredient in a formula does not immediately change the product’s mass
as it is saved in the database.
Number of ingredients – This is a non-editable option. It is updated by the software on adding the next ingredient to a formulation.
Sum – This is the target mass of a formulation, i.e., the sum of all ingredients in a formulation. It is not editable, and it is updated by the software on adding the next ingredient to a formulation.
13.3 USING FORMULAS IN WEIGHING
Depending on the settings, a user working in Formulation mode can move to the formula making process either by selecting a formulation from the corresponding database or by weighing a mixture “manually.”
Preparing mixtures can be done by:
Preparing a formulation that is not saved in the database of formulas, or “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 with
the multiplier function.
Preparing a formulation that is saved in the database of formulas and determining the target
mass of the complete formulation.
Caution: Using the above options requires enabling the corresponding quick access keys in the bottom bar and the setting corresponding options in the formulation mode.
On selecting a formulation, weigh each of its ingredients. When each measurement result is stable, press >. The mass of each ingredient after pressing > is zeroed and accepted for the
total mass of the formulation.
Pressing > cancels the formula making process and allows the user to select another formulation making process.

15 PIPETTE CALIBRATION
The balance allows for pipette calibration using either special balance software or in cooperation with “Pipettes” computer software for pipettes calibration.
Before pipettes calibration, a special set must be mounted inside the draft shield. The set is not standard balance equipment. See the illustration below for set assembly instruction.
The evaporation ring minimizes measurement errors as a result of liquid evaporation during the weighing process.
Page 61
61
Before pipettes calibration, distilled water must be poured into the evaporation ring. The amount of water should not exceed 2/3 of the ring height.
The set may be operated after about an hour. This period of time is required for moisture stabilization. Remember to control the level of distilled water—the surface of the vessel should remain covered with it. Excess of water may be removed with an automatic pump or external pipette.
To minimize both changes of moisture content inside the weighing chamber and negative effect of air blowing in when the chamber door is opened, the liquid should be dosed with a pipette through the opening in the top cover of the weighing chamber.
The Pipette calibration working mode determines volume measurement errors in piston pipettes in accordance with standard ISO 8655 or according to user requirements.
For calibrations carried out in accordance with standard ISO 8655, the errors are automatically selected to tested volume as specified in the standard (see the table of errors for standard ISO
8655).
This 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 errors (accuracy error)  Random error CV (repeatability error)
Carrying out automated measuring procedures by pipette type  Storing calibration results in a database of reports from the calibration process  Printing reports from the pipette calibration process  Exporting reports from tests
During volume testing, the software determines the accuracy and repeatability errors for the tested volume.
For pipettes with adjustable volumes, the software enables declaring up to 5 volumes from the pipette’s total range, which are checked during calibration process.
To ensure the highest accuracy of pipettes calibration process, maintain the following ambient conditions at the workstation:
Ambient temperature of a pipette, tips, and liquid should be between 20°C– 25°C with
change rate during testing within ± 0.5°C.
Relative humidity should be between 50–75%.  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 is 2 hours.
Page 62
62
While calibrating, the balance user will refer to the database of pipettes, which includes data on the pipettes, their parameters, tested volumes, and values of errors determined for specific volumes.
Before carrying out the calibration process, load the database with data on pipettes and calibration criteria.
Adding pipettes can only be done from the database level. This procedure is described later in this user manual.

15.1 ADDITIONAL SETTINGS OF PIPETTES CALIBRATION MODE
The additional settings enable users to adjust the working mode for their needs. To access the setting follow below procedure:
Touch the gray workspace area.  The display shows the following menu: Settings, Keys, Information, Printout, and Profile.  Press the <Settings> key.  The display indicates functions related to calibration of pipettes.
Pipettes calibration is related to the following functions:
Number of measurements: This option determines the number of measurements for the
tested volume of a pipette (valid for each tested volume in the case of a pipette with adjustable volume).
Request serial number: YES/NO. If YES is selected, then before starting the calibration
procedure the software displays an onscreen keyboard for entering the serial number of a pipette.
Comply with ISO 8655: YES/NO. If YES is selected for tested volumes, during the
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 <Comply with ISO 8655>, the error values are neglected and replaced by those from ISO standard).
Acquire data on ambient conditions from THB module: YES/NO. If YES is selected, the
software automatically and at a specified moment acquires and saves the ambient conditions parameters from a connected THB module. If NO is selected, then before starting and after completing the pipettes calibration process, the operator should manually enter the 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 part 10.8, “Additional parameters on weighing process.”
15.2 PIPETTES CALIBRATION QUICK ACCESS KEYS
Each working mode features a set of default quick access keys that are automatically displayed on mode activation. The set of keys can be modified by selecting other quick access keys in the bottom bar of the display. This process requires the appropriate operator’s access level.
15.3 ADDING A PIPETTE TO THE DATABASE OF PIPETTES
The database of pipettes contains a list of pipettes’ names and other data, including tested volume and error values for a specific volume. When adding a pipette to the database, first specify its name and then add other data.
The software operates intuitively and instructs the user to follow displayed information. Adding a pipette to the database can be done in the database’s menu.
Page 64
64
Procedure:
Enter submenu < Databases> and press Pipettes>.
Press Add> soft key to add a new pipette.
The software automatically adds a new entry to the database and enters its editing mode. Enter all parameters of the new formulation.
List of parameters defined for a pipette:
1. Name: press <Name> to open a screen for entering the name of a pipette
2. Code: for entering pipette’s code
3. Model: for entering model name of a pipette
4. Tip: for entering name of used tip
5. Type of volume: ADJUSTABLE/FIXED
6. Nominal volume: for specifying nominal volume of a pipette
7. Minimum volume: for specifying the minimum volume of a pipette (for a pipette with fixed volume, enter <0>)
8. Number of channels: for specifying number of pipette’s channels (for a single-channel pipette, enter <1>)
9. Type: NONE/A/D1/D2. Pipette type is compatible with the applicable standard. Selecting the 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 the type of a pipette.
10. Tested volumes: Opens a screen with a list of calibrated volumes (for a new pipette, the list is empty), add volume to be tested, and define error value for each tested volume:
Press Add> soft key.  An onscreen numeric keyboard is displayed.
Enter value of tested volume in [µl] and accept by pressing >.  A new record is automatically added to the list with recommended error values.  To change error values, press the field with the added volume of a pipette.
Each field is editable and enables entering user values.

15.5 ACTIVATING PROCEDURE
The pipettes calibration process requires installing an adapter for pipettes calibration. The adapter does not come standard with the balance.
The adapter for pipettes calibration is a simple supplementary device designed for calibration and checking of piston pipettes on balances.
The adapter has been designed to minimize evaporation occurring in liquid handling procedures. It consists of a minimized weighing chamber installed inside the weighing chamber of the balance. The adapter features an evaporation ring and a dedicated weighing pan for central locating of the measuring vessel.
The adapter for pipettes calibration prevents liquid from evaporating during the calibration process. The small dimensions of the adapter combined with the evaporation ring maintain a high humidity rate inside the weighing chamber and the measuring vessel, thus stopping the liquid evaporation process.
Our research has proven that the adapter eliminates or considerably reduces liquid evaporation, which is essential for the correct gravimetric calibration of piston pipettes. Selecting an appropriate adapter and balance mostly depends on the type of calibrated pipettes.
Before starting the pipettes calibration process, assemble the adapter inside balance’s weighing chamber and enter data on pipettes to be calibrated, including complete pipette characteristics and values of errors (refer to the database of pipettes).
The next step is setting the process’s main options:
Number of measurements  Request batch number (YES/NO)  Operation with ISO 8655 (YES/NO)  Acquire ambient conditions from THB.Y module (YES/NO)
After setting the above options, go to pipettes calibration process.
Procedure:
Press the Select pipette> key.  Select a pipette for testing from the displayed list.  On selecting, the software returns to the main screen and the name of the selected
pipette is visible in the gray workspace area.
Press the Start> key in the bottom bar of the display.  If “Request batch number” is enabled (set to YES), a screen opens for entering the
batch number and accepting the value.
A new screen opens for entering the values of ambient conditions read from the external
sensors (temperature, humidity, pressure and water temperature). After entering these
Page 67
67
values, press Accept>. If “Acquire ambient conditions from THB module” is enabled (set to YES), the software automatically acquires data from the THB module on temperature, humidity, and atmospheric pressure. The value of water temperature has
to be entered manually and confirmed by pressing Accept>.
The software returns to the main window, and the gray workspace area displays the
following data: Tested volume and Process status “In progress.” The task bar displays
commands and hints for the user on the next step, “Weighing sample C1/V1/N1.”
Description of texts: C1 – channel number; V1
number of volume for a channel; N1 – number of measurement for the tested volume.  Follow the displayed instructions until the calibration process is complete. The gray
workspace area displays other data on calibration process, i.e. average volume, values of errors, specific to the completed process.
On accepting the last measurement, a screen is displayed with ambient conditions
parameters. Proceed as on process start: enter all ambient conditions parameters and press Accept>.
The software automatically generates a report that is printed and stored in the database
of reports for pipettes calibration (ambient conditions and water temperature values given in the report are averages from the initial and final values of a process).
Complete the process by pressing the > key in the bottom bar. For multichannel
pipettes, the balance displays a message on continuing the process for the next channels. On confirming the message, the balance carries out calibration/testing process for the next channel. The settings remain unchanged.
The software allows the user to start the next procedure for the same pipette or select
another pipette from the database.
15.6 REPORT ON THE COMPLETED CALIBRATION PROCESSES
On completing each calibration process, a report is generated. The report is saved in the “ Reports from pipettes calibration processes” database. The files are named using the date and
time of the calibration process.
An example of a report on pipette calibration process:

16 DIFFERENTIAL WEIGHING
The Differential weighing working mode analyzes changes of mass in a single sample or multiple samples.
The process is performed by determining the sample’s initial mass, and then the sample is subject to
different processes, whose outcome is separation or addition of some of the sample’s ingredients.
Finally, the sample is repeatedly weighed (differential weighing). After the final weighing, the balance determines the difference between the two mass values, initial and final.
The balance in differential weighing mode enables:
Determining a series, where each series may contain several samples  Assigning a name for each weighed sample and printing or exporting data on a series to a
connected data storage device
Determining tare value and initial mass for each sample, and performing up to five
measurements for the final mass
If balance users need to use the differential weighing mode, then initially they need to enter data on a
weighed series to balance’s database, define the samples in a saved series, and then recall a saved
series for weighing. The series are created at the databases level. The series-creating procedure is described later in this user manual.

17 STATISTICAL QUALITY CONTROL
The Statistical Quality Control working mode performs different types of product packing processes and monitors and/or controls the packing process. It detects excess or lack of product quantity in a package. If the samples have been weighed and the results are stored in the database, then the software discerns a trend and displays them in a form of a chart. The software is able to control a batch comprising up to 1,000 samples.
Each completed control process is saved in the SQC database, and its results are available for preview. Each series has a determined set of parameters that are stored in the database: maximum, minimum, standard deviation, and average value for each batch.
SQC control process can be performed manually by pressing the <PRINT> key for each measurement or automatically, where the measurements are saved after stability is indicated for each measured sample.
The balances feature an implemented module for statistical control processes. It is supported by a database containing a list of products with error values <–T1> and <+T1> declared for each product.
The control process is initiated automatically and completed on controlling a required quantity of samples, which is determined by the user in the SQC mode settings.
