In non-verified balances all measuring units including those outside the International System of Units are available. 10.2. Means of correct weighing procedure In order to ensure long lasting use of a balance, 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 maximal capacity). ? Load the weighing pan steadily avoiding shocks: YES NO ? Place weighed loads centrally on the weighing pan: YES NO ? Avoid side loading, in particular side shocks: NO NO - 22 - 10.3. Balance levelling Balance Y2 series features AutoLEVEL System, which continuously monitors balance’s level status during its operation. The level status is signaled in the upper right corner of balance’s display. The system continuously controls level, and on detecting level change it indicates appropriate information on the display and/or signals an alarm. Then the software opens a window for adjusting the level. Balance levelling procedure • Press level status pictogram< > located in the upper right corner of the display. • The display indicates a control panel of leveling function. Balance operator previews level status, and balance’s top elevation. • Level the balance by turning the adjustable feet in a way indicated by blinking pictograms on the display < > – the level point should move towards the center of the level circle. • As the level point is in the center point, its colour changes from red to green – which is a confirmation for correct level status. Caution: The balance is equipped with Automatic Level Control mechanism. Description to be found in point 33.7 of this manual. 10.4. Zeroing In order to zero mass indication press key. The mass indication on the display should equal zero, and precise zero and stability markers should appear. Zeroing process is tantamount to determining new zero point recognized by the balance as precise zero. Zeroing is possible only in stable status of display indication. Caution: Zeroing the display indication is possible only within the ±2% range of instrument’s maximal capacity. If zeroed value is above the ±2% of the maximal capacity, then the software indicates an error message Err2. - 23 - 10.5. Tarring In order to determine net weight of a weighed object, place object’s container (packaging) on balance’s weighing pan, and on stabilization of measurement result press key. The display should indicate mass equal to zero and symbols: Netand . On taking off the weighed load and its packaging from instrument’s weighing pan, the display indicates sum of total tarred mass with minus sign. The software also enables assigning tare value to a product from a database. Then, on product selection from a database, the software automatically uploads data on tare value for the specific product. Caution: Tarring negative values is impossible. On tarring negative values the balance responds with an error message. In such case zero balance’s indication and repeat tarring procedure. Manual tare determination Procedure: • While in optional mode press quick access key , • Which opens numeric keyboard on balance’s display, • Using numeric keys insert desired tare mass and press key, • The balance returns to weighing mode, and the display indicates inserted tare value with minus “–“ sign. Deleting tare The tare value indicated on balance’s display can be deleted by pressing ZERO key on balance’s front panel, or using programmable function key PROCEDURE 1 – on taking the tarred load off balance's weighing pan * Press ZERO key * The NET marker is deleted, and new zero point of the balance is determined PROCEDURE 2 – when the tarred load in on balance’s weighing pan * Press ZERO key * The NET marker is deleted, and new zero point of the balance is determined * If tare value exceeds 2% of balance’s maximal capacity, the display indicates error message –Err- (forbidden operation) PROCEDURE 3 - when the tarred load in on balance’s weighing pan or on taking the tarred load off balance's weighing pan * Press programmable key * The NET marker is deleted, * The display indicates tare value * Press key to restore the last tare value - 24 - 10.6. Use of air buoyancy compensation factor 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 Sample mass [g] Error value in relation to density of weighed sample 1. 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. - 25 - FUNCTIONING The application provides two ways to use the air buoyancy compensation procedure. 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 conmpensation mode is enabled / disabled from the level of user menu. The application is operating in weighing mode only. STARTUP AND OPERATION OF AIR BUOYANCY COMPENSATION PROCEDURE • While in main window press grey coloured workspace • Select option • Select parameter < Air buoyancy compensation> Accessible settings - Air buoyancy compensation – 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 - 26 - value used for calculating buoyancy correction factor. 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 operation 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 module 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. Caution: If the mode is set to value, then balance display does not indicate pictogram <> which means that parameter Setup/Ambient Conditions/Ambient Conditions Module is - 27 - 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. 10.7.

WORKING MODES – general information A balance 3Y series 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 and high threshold . Dosing Means of operation: a user should specify sample’s target mass to be obtained by pouring. Percent setup 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 standard (reference). 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. Formulation 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 specifying its ingredients and their mass. Statistics Means of operation: carried out measurements are used to calculate statistical data, such as Min, Max, deviation, etc. Pipette calibration Means of operation: calibration of pipettes according to procedures listed in ISO 8655 or according to user requirements. - 47 - Differential weighing Means of operation: analysis of mass sample change over time.

Unless this condition is met, the balance displays a message: ; • Mass of a single part must not be lower than 0,1 of balance’s reading unit. unless this condition is met, the balance displays a message: . 16.5. Acquiring part mass from database A product record in the database of products features set of information which identifies it. One of them is mass, which is used during part counting process. Procedure: When in working mode < Parts counting> press < Products database> key, and then select desired product from displayed list. Insert standard (reference) mass to balance’s memory Procedure for adding standard (reference) mass of a single part to the database of products: a) Press < Setup > key followed by pressing < Database > key b) In the Database of Products press < Products > c) Press name of a product and edit data in field no. [5] Mass d) Return to mode. If there are no data in the database: a) Press < Setup > key followed by pressing < Database > key b) In the Database of Products press < Add > key c) Accept the process of adding a new record in the database d) Fill in field referring to a product, including field no. [5] Mass e) Return to mode. - 57 - 16.6. Updating part mass in the database Determined mass of a single part can be assigned to a product in the database of products. This option is applied while using ACAI (Automatic Accuracy Correction) function in order to determine part mass with high accuracy. Procedure: a) Determine mass of a single part b) Press < Database> key c) Press and hold finger on name of a product, which mass is updated, d) Contextual menu is displayed, e) Select option , reference mass is saved in a product record under entry . 16.7. Parts counting procedure The first step in parts counting mode is obtaining data on mass of a single part. Select one of available options: - Give mass value of a single part (see point 16.3) and place parts on balance’s weighing pan, balance displays totalized parts. - Set mass of a single part from a given quantity of parts (see point 16.4.), the balance additionally shows pictogram of the ACAI function < > (if enabled). Place parts on balance’s weighing pan, the balance displays totalized parts. - Acquire mass of a single part from database of products (see point 16.5.) by selecting a desired product record. Place parts on balance’s weighing pan, the balance displays totalized parts. Caution: All additional elements (i.e. packaging) have to be tarred before starting the parts counting process. - 58 - 16.8. Checkweighing function in parts counting mode Proces liczenia detali moze byc wspomagany funkcja dowazania czyli kontroli czy wskazanie miesci sie pomiedzy progami akceptacji. Checkweighing requires setting values of two thresholds, described as: - LOW threshold [Min= … parts] - HIGH threshold [Max= … parts] and enabling bargraph (set its attribute to YES), which displays below relation: CURRRENT NO. OF PARTS / CHECKWEIGHING THRESHOLDS. Defining the values of Low and High thresholds is carried out in the Database of Products while editing Product entry, or using a quick access key < Defining thresholds>. Procedure • Press grey coloured workspace and press option • Set Bargraph option to YES, return to parts counting mode • Press grey coloured workspace and press option • Assign option to one of the quick access keys displayed in the bottom bar • Return to parts counting mode • Press < Checkweighing thresholds> key and insert values for LOW and HIGH thresholds, return to parts counting mode • Under the measurement result there is bargraph displayed.
