Functions:
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 bar graph - load indicator. For industrial scales it is possible to use a control systems of dosing process.
Labeling - Marking products with the right symbols contributes to quick and reliable identification. The balance/scale usually transfers product mass or product quantity to the label printer. The transferred value is printed with the following information: bar code, pictogram, content, address etc. In laboratory the labeling is performed in a semi-automatic mode, for industry in an automatic one (dynamic scales).
Plus/Minus Control - Control of sample's mass carried out with reference to specified MIN and MAX thresholds. The weight is considered to be correct if it is comprised within threshold values. A graphic visualization of weighing result is displayed in a form of a bar graph.
Percent Weighing - Percent Weighing function is used for comparison 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.
Totalizing - Function adding new mass value to already obtained one. This allows to determine mass content of the mixture, being a composition of number of different consistence components. Totalizing is limited by maximum capacity parameter.
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 supported 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 signaling base informing that specified number of items has been weighed. It is possible to apply weighing systems using few platforms of different MAX capacities and different accuracies.
Peak Hold - Function registering the greatest temporary indication occurring in course of the weighing process. It is most often used in medical scales in order to hold the measurement indication.
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.
Newton Unit Measurement - Function allowing to perform the measurement in Newton unit, it may be used for processes aiming to determine force resulting in the sample damage.
Statistics - Statistics function registers and analyses performed measurements. This supplies the user with the 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 High [HI]. The thresholds are given in [g] and [kg] units. Current state of a sample being measured is signaled by means of pictograms located on a display for laboratory balances, for industrial scales Stack Light 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 specified 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.
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.
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. In such case standard 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.
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.
AP2-1 Current Loop unit 4-20 mA has been designed to convert digital value of mass to analog value. It is a unit of passive type, i.e. it requires to be supplied with power from an external source, of 24 VDC voltage value.
Additional display WD-4/4 series is designed for cooperation with scales and weighing systems based on terminal PUE 7. The data indicated on the additional display, correspond to those present on scale's display. The WD-4/4 series can function as data indicating display of main weighing platform or additional weighing platform. Additional display WD-4/4 is manufactured in plastic housing. It features LED display, and it is connected to a terminal PUE 7 series through a cable with D-SUB 15 (male) socket. The additional display is powered from the terminal (scale). The WD-4/4 is equipped with automatic display blanking function and automatic detection of the baud rate. Area of Use: Designing of load cell based industrial scales. Increasing the functionality of scales based on terminal PUE 7 series.
