Beregning af måleusikkerhed/MSA analyser

The evaluation of machines, production facilities and current manufacturing processes is based on the statistical analysis of characteristic values. Processes measuring predefined characteristics provide these values. In order to avoid misinterpretations, the recorded measured values have to be reliable reflecting the real conditions, i.e. measurement processes have to be capable of performing the demanded task in the respective situation. solara.MP is the perfect choice to establish measurement process capability.

Measurement system capability according to MSA

Suitable measurement processes are required to achieve beneficial results. The MSA (Measurement Systems Analysis) reference manual often provides the basis for this decision. solara.MP is the tool of choice for instrument and gauge capability.

solara.MP conducts necessary capability studies to establish measurement system capability. The main differences between generally accepted studies such as type-1 (Cg/Cgk), type-2 and type-3 studies (%GRR) or linearity and stability analyses are the applied calculation methods and the respective limit values. The software encompasses the procedures given in the MSA manual of the AIAG Core Tools and many other guidelines of the automotive industry.

Capability analysis according to VDA 5

Measurement processes are affected by a variety of influence quantities. Many standards thus demand the calculation of measurement uncertainty. VDA Volume 5 offers a practical approach and solara.MP helps to implement it easily and intuitively.

The calculation of measurement uncertainty is based on an approach that is quite as pragmatical as a MSA capability analysis; however, it follows the specifications of GUM (Guide to the expression of uncertainty in measurement) or EN V 13005. solara.MP thus combines uncertainty components into an uncertainty budget and calculates the expanded measurement uncertainty U.

Measurement uncertainty according to GUM

While the “Guide to the Expression of Uncertainty in Measurement (GUM)” explains the theoretical backgrounds of the calculation of expanded measurement uncertainty, solara.MP actually creates an uncertainty model for every inspection process for immediate visualization. solara.MP will display the relationship between the uncertainty components in a clear flow chart with each box representing an uncertainty component. These uncertainty components can be edited with a mouse click. The combined standard uncertainty and the expanded uncertainty is calculated based on input of an intuitive logical operation formula.


Regardless of the methods you use and whether you conduct capability analyses at a test station, production line or in a test laboratory, solara.MP makes sure to provide you with the most reliable and actionable information you need!

Udvidelser (Extensions)

The following functionalities are a perfect extension to the Q-DAS software product solara.MP:


solara.MP is available in 22 languages. One click is all it takes to switch the language of a specific view. Employees working in different plants all over the world may apply Q-DAS software in their own language.

Form Designer

Q-DAS Form Designer makes it easy to create and modify available report templates. You may apply these templates in any Q-DAS software product. The interaction with M-QIS helps you adapt reports to the specific requirements of your intended recipients. Select from a tool box of texts, statistics, parts data, characteristics data and additional data as well as graphics (qs-STAT graphics and image files in the BMP, JPG, EMF and WMF format) and add links and logical operation formulas. Use drag-and-drop functionalities to position these elements in a report.

3D CAD Viewer

CAD models offer visual support in performing measuring tasks. The integrated reporting system illustrate test results and evaluation results based on a CAD model.

3D CAD providing the basis for test plans

With a test plan available in qs-STAT and measured values recorded, you may assign characteristics to the CAD model after selecting them.

Supporting data recording

Approved as tools for the real-time visualisation of results and SPC alarm control, the tool is now even designed to show characteristic-specific views in the CAD model. It guides the operator perfectly through the measuring task.

Reports including 3D CAD

The CAD models serve their purpose in many fields of statistical analysis; they can even be used in reports. Individual and customised reports refer to the respective CAD model. Since the features/characteristics are allocated to the drawing, the report automatically shows the relevant characteristics in the CAD model together with associated evaluation results.

Web service

Functionalities in a web browser

Web solution for Q-DAS software products do not have to be installed on a computer but run on an Internet browser.

solara.MP Web

The web component of solara.MP is the perfect choice to perform measurement system analysis tasks. Just like solara.MP, the web application includes MSA studies and the calculation of statistics based on corporate guidelines. Users may look at already conducted studies and navigate interactively through the web interface. They open individuals and summary graphics and show, move or scale them as individual elements.

Q-DM Datamanagement

The Q-DAS database forms the basis for statistical evaluations in qs-STAT. Only the database makes it easy to compare different information (machines, orders, etc.) and evaluate them automatically in M-QIS Engine.

Transfer of data

Q-DM is typically installed on a server in your network, sometimes even as a service. It monitors directories cyclically storing Q-DAS files. As soon as you store a file in a directory you Q-DM monitors, the systems saves its contents to a Q-DAS database. This process is based on defined rules you adjusted in Q-DM; these rules ensure a clear allocation of measurement information in the database.

You may adjust a wide range of settings, e.g. how to respond to alarms occuring while loading files in the database and store specific information to be considered in subsequent evaluations. The tool is able to generate protocols when a problem occurs while transferring data, e.g. due to a missing network connection or erroneous files and sends them to system administrators by email. The major task of Q-DM Datamanagement is to guarantee a smooth data flow.


In case your data are not available in the Q-DAS data format, you may apply a converter in Q-DM. It converts the foreign format into Q-DAS files and loads them in the database.
