ScalesNet History

Connecting Balances by Network - A leading Weight Calibration Software

The next development stage was defined by the requirements of weight manufacturers and was performed with the support of Mr. Haefner (Haefner Gewichte GmbH company). The new product was renamed to ScalesNet32 and  put into production in 1999 at the Haefner Gewichte GmbH company.

With increasing international clients, the requirement arose to integrate a UNICODE SQL database into ScalesNet. A new ScalesNet version with integrated UNICODE database was released in 2004.

The latest overhaul and restructuring of ScalesNet was performed in 2010. ScalesNet was divided into modules. This ensures better customization options to adapt ScalesNet to customer demands. The current ScalesNet version has been  renamed to ScalesNet-M (Modularity).

ScalesNet-M is undergoing continuous development, accommodating the requirements of the target markets and to enhance the product's capabilities. This allows adaptation to ever changing customer demands.

ScalesNet-M ensures that all calibrated weights can be traced to a defined National Standard and are in compliance with quality management requirements.

Databasemodel
  • ScalesNet is based on the "thin client/fat server" model. This means as many processes as possible run directly on the server, rather than on the client machine. The database logic is represented on the server
  • No data records are deleted. Each data record has a "Deleted" field. This field is set to 0 when active, and is set to 1 when the record is marked for deletion. As is the case with all changes in the database, the deleting of a record is noted in the log file
  • Every time parameters in a data record are changed, a new record is created and the previous version of the record is marked for deletion. Simultaneously, an entry is record in the log file with references to the new and old data record
  • The log file also contains the name of the table, type of access, date and time of access, user ID, etc
  • When a report is created, the data record for that report contains the IDs to all data records required for generating the report. This means the report can be printed out at any time without having to save all the calculation results. Later modification of the data (for example, calibration of the weighing instrument is renewed) does not affect the record retroactively
Important

All installations for customers contain identical program codes. ScalesNet does not contain any customer specific program codes. Access rights to program sequences are controlled by programmable Hardlock.

Functions of ScalesMass

Calibration of Customer Weights (Test Pieces)
General Information

Calibration of test pieces is processed on the basis of a work order. This work order lists the job number, customer name or numbers, weight or weight set to be tested, type of test, mass comparator used, reference weight set and type of report. These data must be entered, or selected from the available data, before beginning the test. Supports also optional sensitivity weights and check weights. When robotic weighing instruments are used, a job can be defined for each magazine (weight platform for automatically loading weights onto the weighing instrument) encompassing n work orders, n serial numbers, the reference weight and the number of weights to be tested. This program sequence also includes the display of mass scales.

Calibration Calibration
Calibration of Reference Weights
General Information

Data on references weights are entered in the base data for administration. In the calibration of reference weight sets, a distinction is made between external and internal calibration. All reference weight sets that require internal calibration are listed under Work order\Internal\Reference set, and can be calibrated internally in accordance with the specified guidelines. During internal calibration, the sequence is the same as for calibration of customer's weights, with the exception that no customer is selected. For reference weight sets requiring external calibration, data can be updated in the base data, with calibration date, calibration certificate number and calibration instance, by clicking on the "New calibration" button; the "Deviation" and Uncertainty" fields are cleared.

Dissemination of mass scale
General Information

Calibration of test pieces with Dissemination of mass scale is processed on the basis of a work order. This work order lists the job number, customer name or number, weight or weight set to be tested, type of test and type of report. The test pieces used in Dissemination of mass scale are not always from a single work order; for this reason, a job must be defined (similar to that described above for the robotic weighing instrument) that contains all work orders, customers and test pieces. Once this job has been defined, the weighing plan must be selected and the data pertaining to the weights (customer no., manufacturer, serial no., etc.) entered in the plan. The comparisons defined in the weighing plan form the basis of the comparative measurements to be performed on the weights. Result are in the entered matrices and calculated, and the values yielded are allocated to the individual weights. When robotic weighing instruments are used, multiple jobs can be defined for each magazine (weight platform for automatically loading weights onto the weighing instrument) encompassing n work orders, n serial numbers, multiple reference weights and the weights to be tested.

Wägschema
Quick Comparison of Weights
General Information

Select this menu item to perform a quick test. This feature lets you compare a test piece ether to a reference weight or to a manually entered value, for comparison without placing a reference weight on the weighing instrument. This test is not recorded in the database, but the data obtained can be exported for further processing with MS Excel.

Manual Input von Weighing Data
General Information

This module is for weighing instruments that do not have a data interface. The weighing instrument is defined in the base data and the operating mode "manual operation" is selected. Calibration of weights with this module is distinguished by manual input of weighing data. Subsequent calculations and printouts correspond to those described under "Calibration of Customer Weights (Test Pieces)."

Calibration of the Weighing Instrument
General Information

Calibration of the weighing instrument yields an sp value which can be used as the basis for calculating the permissible class. Calibration is performed at defined intervals. The intervals and a "grace period" are defined in the base data of the weighing instrument. When the calibration interval has elapsed, the weighing instrument is marked by a yellow symbol in the tree diagram, and the weighing instrument remains available for use during the grace period. If calibration is not performed before the grace period has elapsed, the instrument is marked by a red symbol and blocked from further use. When the ScalesMass program is run, a message window shows the weighing instruments for which the grace period is active or which are blocked from further use pending calibration.

Adjusting the Weighing Instrument
General Information

Adjustment of the weighing instrument is performed at defined intervals. The intervals and a "grace period" are defined in the base data of the weighing instrument. When the calibration interval has elapsed, the weighing instrument is marked by a yellow symbol in the tree diagram. If calibration is not performed before the grace period has elapsed, the instrument is marked by a red symbol and blocked from further use. The next time the program is run, a message window shows the weighing instruments for which the grace period is active or which are blocked from further use pending calibration. The distinction between internal and external calibration/adjustment affects the sequence of the procedure.

All employees using ScalesNet must be registered in the data base by name and their password.

Material of weights

Data of the weight standards used are stored here. All relevant settings/given points for the defined standards (for example OIML R111, ASTM E617, NIST, etc ) are defined in this section.

Climate Stations

The data base lists all climate stations and the respective sensors necessary to collect all room parameters necessary.

Shape of the Weights

The data base contains the shapes of the weights.

Orders

The work orders are shown in a tree pictograph. All recorded and active orders are shown in the tree pictograph as . Closed orders are moved into the archive and are identified with the symbol . An order is considered closed when a test certificate, a calibration or an other certificate was generated. The order then is placed into the grace period (default 7 days) and is marked asl . The grace period serves as extra processing time for shipment. Should a weight during this time get damaged, then the weight set can be re-activated under the same work order number and the defective weight can then be replaced.

ScalesDesk
Preparing Reports and Records
Type of Report or Record

Reports and records are used for printing measurement data and header data. A distinction is made between internal and external reports or records.

Internal Records

Folgende Protokolle sind interne Dokumente:

  • Test piece calibration record
  • Protocol for results of Dissemination
  • Inventory list for the weighing instrument
  • Inventory list for the reference weights
  • Inventory list for the climate stations
  • Record of results from weighing instrument calibration

These records are made available in the form of MS Word templates, with bookmarks representing measured values or texts. These bookmarks are replaced by the corresponding value or text when the record is printed.

External Records

The external records are Word templates generated by the user. The required bookmarks are presented in a list for selection by the user; users can also add bookmarks for user-defined text passages. All bookmarks that represent text passages can be generated bilingually in this report. The language setting is saved along with the report (Word template). This makes it possible to create DKD calibration certificates in a variety of language combinations (e.g., German / English, Italian / English, etc.). Because the report uses a Word template, graphics can be inserted as well; for example, to add a logo, signature, stamp, etc. Bookmarks for out of tolerance, adjusted and replaced weights (as found and as left) are available.
