CE - Information about conformity of a product with European Union regulations that concern the product. Marking the product with CE sign makes the manufacturer responsible for the product to meet requirements of general safety regulations determined by CE marking directives.

Verification - The procedure within the scope of Legal Metrology. It is performed by regional Offices of Measures or authorized entities before the new product is introduced to the market. The procedure is performed on the basis of tests validating conformity of a product with the directives. For most measuring devices, including balances and scales, this procedure has been replaced with declaration of conformity.

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.

Density determination

Liquid or solid body density function uses the Archimedes principle and it requires a special kit to be applied. The kit when used, replaces a weighing pan. For solids mass of the sample must be determined first in the air, next in the liquid of specified density. For liquids the so called sinker, density of which has been determined, must be measured first in the air, next in the tested liquid. The density determination process is disturbed by air bubbles which may stick either to the measured sample or the sinker. In case of laboratory equipment very light solids may be measured. For industry, solid bodies density may be determined by means of under-pan weighing. Tested load of significant size may be measured this way.

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.

Statistical Quality Control

Statistical control for determination of basic statistical criteria: maximum, minimum, standard deviation, mean values for each batch, etc.

Packaged Goods Control

Pre-packaged Goods Control mode enables to collect weighings from RADWAG-designed weighing instruments, carry out control and generate PGC reports. Different types of weighing instruments can be combined into a network. The control can be started on a balance or via computer software. It is automatically finished after a respective quantity of packages is verified.
Collected data allows you to assess quality of produced pre-packaged goods and their conformity with:
- internal quality control system;
- 'Pre-Packaged Goods' regulation of 7th May 2009 (Journal of Laws No 91, item 740), on the requirements concerning quantity inspection of pre-packaged goods control, which inspection is to be carried out by means of random selection of the measurements results and sending those results to pre-packaged goods control procedure.

h3{display:inline color:inherit font-weight:inherit}PS 3Y balance has an implemented module for control of packaged goods, which is supported by a database with list of operators and products. An effect of a control is a final report printed on a dedicated printer connected to the weighing set. The cycle of control runs with the following schema: choice of material choice of operator start of control collecting measurements automatic finish of control after taking set quantity of measurements print of report from the control. PS 3Y balance is equipped with 5,7'' touch screen display, which indicates current stage of running control and its result. Each performed control is finished with a report which can be printed on a dedicated printer. PS 3Y balance additionally allows for sending the memory content to a computer in random moment of operation. The balance can be operated also by PS/2 keyboard connected to a balance.
