Antistatic Weighing Chamber
XA 4Y.M.A.P PLUS microbalance is a device where the influence of electrostatics onto the weighing result has been eliminated due to use of special antistatic coating of the glass panes, and thanks to an in-built ionizer.
The ionizer neutralises electric charges inside the weighing chamber upon placing the sample in it. The lower 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. The influence of static electricity gives 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. The antistatic ionizer implemented in the XA 4Y.M.A.P PLUS microbalance 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 ionizer operation using weighing instrument panel. The operation is signalled by blue diode which emits light when the ionizer is on.
The XA 4Y.M.A.P PLUS series is equipped with 5.7″ LCD colour touch screen facilitating device operation and presentation of the results. Complex databases enable users to register, print and export measurements. The weighing instrument system supports 13 languages.

Ergonomic Mechanical Design
Latch-type system of weighing chamber components fastening allows easy and tool-free assembly/disassembly which facilitates keeping the chamber clean, and which makes it easy to install a manual adapter for pipettes calibration.
Smart system of pressures equalization guarantees stable measurement. It eliminates errors generated by rapid change of pressure inside the weighing chamber. A real novelty is an option of lighting the weighing pan up using a LED diode. The diode does not affect the weighing chamber temperature.
Door Opening Automation
The innovative weighing chamber system for door opening and closing guarantees smooth and quiet door movement, and eliminates vibrations that may disturb the measurement. The solution enables to define how wide the door is to be opened.
Pipettes Calibration Adapter
The pipettes calibration adapter enables calibration and/or verification of piston pipettes by means of gravimetric method. It is operated automatically using IR sensors. Evaporation ring is an integral part of the adapter that increases relative humidity inside the weighing chamber. With this evaporation of the liquid during weighing process is stopped.
Use of the pipette calibration adapter reduces maximum capacity of the balance by the mass of the weighing vessel.

FUNCTIONS
AUTOTEST
Diagnostic function aiming at metrological parameters determination (repeatability), the parameters are determined for the actual conditions of use. When speaking of repeatability it may be also used for weighing time optimization. Autotest is operated in an automatic mode thus operator’s time is saved.
DOSING
Weighing process for which reference mass has been determined together with tolerance for its determination. Dosing tolerance is given in [%] and it is calculated in relation to the reference value thus being a permissible deviation of this process. This solution is used for weighing powders, liquids and loose materials. Dosing function performance is often supported with bargraph – load indicator. For industrial scales it is possible to use a control systems of dosing process.
PERCENT WEIGHING
Percent Weighing function is used for comparision of measured products with mass standard. Mass of a mass standard may be a numeric value taken from a database or it may be determined through a measurement process. Each measured product is compared to mass standard, mass of which is presumed as a model 100% ideal mass. For products weighing less than the mass standard, obtained results are lower than 100%, for products weighing more, the obtained results are greatly exceeded.
PARTS COUNTING
Function using mass measurement for determination of measured items quantity. Mass of a single item is required for this process. It may be either estimated through weighment or taken from a database. For items counting the following algorithm is used: all items mass / single item mass = quantity. Function operation is supperted by a mechanism of Automatic Correction of Accuracy. This allows to update single item mass in course of the process. To a certain extend Automatic Correction of Accuracy eliminates error which may be a result of different mass values of seemingly alike single elements. For industry solutions items counting may be simultaneously carried out with checkweighing and dosing thus industry solutions feature audio signalling base informing that specified number of items has been weighed. It is possible to apply weighing systems using few platfroms of different MAX capacities and different accuracies.
FORMULATION
Function supporting the mixture making process, wherein the mixture contains various components. Formulation function usually uses the balance/scale database of components. Formulation serves for monitored checkweighing of every single component with a given tolerance. It is enriched with a set of individual settings.
STATISTICS
Statistiscs function registers and analyses performed measurements. This supplies the user withthe following information: Max and Min standard deviation, average value, variance, range et.
CHECKWEIGHING
Checkweighing function is used for checking whether the measured sample mass is within the predefined threshold values, Low [LO] and Hgh [HI]. The thresholds are given in [g] and [kg] units. Current state of a sample being measured is signalled by means of pictorgams located on a display for laboratory balances, for industrial scales Stackligt System is used. This visual +/- inspection is in operation during segregation, control or packing process of products for which mass has bees determined with a specifaied tolerance, eg. 12860 g 961
IR SENSORS
Programmable function supporting the weighing process through control of the following options: sliding weighing chamber doors, printout, zeroing, tarring etc. Especially appreciated wherever preventing the balance from soiling is important.
GLP PROCEDURES
Diagnostic function allowing to objectively document performed measurements. GLP procedures may be either presented in a short report form or extended one.
ANIMAL WEIGHING
Process of mass determination for a product which may unwillingly reposition within the weighing pan. Mass determination in such cases requires much longer period of time when compared to typical weighing process. It is the user who defines period of time needed for control of measured product mass. The user can thus optimize the function depending on the measured product characteristics.
PIPETTES CALIBRATION
AIR DENSITY CORRECTION
Function performing correction of mass measurement indication, wherein the air density is taken into account. It is used in balances with reading unit < 0,01 mg.
AUTOMATIC SLIDING DOOR
MOVEABLE RANGE
DIFFERENTIAL WEIGHING
Differential weighing informs about mass variation a particular sample, wherein the said variation is a result of manufacturing processes.
Differential weighing is often applied in product control process, for which reference product parameters have been specified in order to be used as a source of comparison for the whole series.
Insuchcasestandard deviation is the information which tells about quality and completeness of a final product. For systems based on a feed-back technique such information may be used by control units.
REPLACEABLE UNIT
Replaceable units.
STATISTICAL QUALITY CONTROL
Statistical control for determination of basic statistical criteria: maximum, minimum, standard deviation, mean values for each batch, etc.
ALIBI MEMORY
“ALIBI” memory enables saving and storing up to 100000 measurements. Measurements are saved automatically upon each pressing of the key. There is no need for any additional operations or changing settings.
The following data related with the measurements is saved: measurement date; measurement time; result (mass); tare value; operator carrying out the measurement (logged in); product name.
The software saves the measurement in a so called loop, i.e. when the measurement no. 100001 is saved, the measurement 1 gets automatically deleted from the memory.
Measurements saved to balance memory cannot be deleted.
You can preview and print out the data saved to the ALIBI database.
WI-FI®
Wi-Fi® offers possibility to send data from balance to a mobile iOS or Android device, via special data management apps. Wireless communication between the indicator and the weighing instrument enables operating the balance that is placed inside a laminar flow hood or a fume cupboard.
