Metrology and MSA

Metrology software is an effective tool for controlling gauges and measuring devices subject to metrological order. It meets all requirements arising from ISO 9001, IATF 16949 and the standard for accreditation of calibration laboratories EN ISO IEC 17025. The methods used are in accordance with MSA 4th edition. The method of assessing the capability of gauges is in accordance with VDA 5.

"Metrology" software is available in four variants:

• Metrology Basic - The simplest variant containing gauge evidence, calibration planning, gauge distribution point, gauge statistics and statistics of costs for external calibrations, dauge capability studies according to VDA 5.
• Metrology Standard - Contains gauge evidence, calibration planning, performing own (internal) calibrations, calibration protocols including error calculation and extended measurement uncertainty, gauge linearity and stability error analysis, gauge statistics, external and internal calibration cost statistics.
• MSA - Includes gauge evidence and tools for the measurement system analysis (MSA) - studies Cg, Cgk, R&R, ANOVA, BOSCH M3 (for automatic machines), graphical analysis, method of control diagrams. The cross-table method and the signal detection method, including the short method, are available for attributive gauges.
• Metrology Professional - Includes all the features of the standard version plus tools for the measurement system analysis (MSA).
• Metrology Mobile Application (OS Androind and WIN) - A support application for mobile devices that is provided as an extension to any version of Metrology software (supports OS Android and WIN). This application is used to quickly find information about a specific gauge in on-line or off-line mode - such as the length and end of the calibration period or the current location of the gauge.

Language versions - In the METROLOGIE software, you can freely switch between the language versions CZECH, ENGLISH, in which it is supplied as standard. In total, you can switch between up to 6 language mutations.

Definition of code lists

To facilitate work in other parts of the program, you will define code lists such as gauge categories, gauge types, product list, staff, calibration centers, calibration procedures, etc.

Gauge records

The "Gauge records" and "Gauge card" are used to record and store the necessary data on the gauge, where, in addition to the basic data on the gauge, you will also find data on calibration, history of use and repairs. The gauge card is connected to the program part of the "Calibration" module and the resulting data from the calibration process are automatically transferred to the gauge card. These are data on the calibration result, calibration date, calibration expiration date, protocol number, measurement uncertainty, etc. The history of external and internal calibrations is automatically recorded. If you have reports from external calibrations in electronic form, you can attach them to the calibration record and then open the calibration report directly from the program.

The program is also adapted for the control of gauges according to individual production plants. When you require employees of a given production plant to have access only to gauges of the same plant.

The program also includes functions for creating your own print reports. And functions for changing the names of items and texts in forms and in already predefined print reports.

Assessment of the usability of gauges

The program includes functions for assessing the applicability of gauges (determination of the minimum tolerance Tmin) in relation to the resolution of the gauge, the expanded uncertainty, the limit value Gpp and the limit rate of resolution. The assessment of the usability of gauges is in accordance with VDA 5.

Calibration

Calibration is a useful tool to ensure proper control and performance of internal and external gauge calibrations.

The basic elements of "calibration" are:

• calibration plan ensuring the selection of gauges with an expired calibration date as of the required date
• recording of monitored (calibrated) dimensions
• actual calibration, including error calculation and extended measurement uncertainty
• display of linearity error in the entire monitored range of the gauge
• the progress of calibrations and display of gauge stability
• print calibration report (possibility to define own calibration protocols)

Gauge distribution point

To record borrowed gauges and record the history of loans, use the functions of the "Distribution point" part of the program. Gauge borrowings are automatically recorded on the gauge card, giving you an instant overview of the actual gauge location.

Measurement system analysis - MSA

The Metrology Professional module contains methods for investigating the suitability of gauges, including methods for attributive gauges. A useful function of this part of the program is to display the performed studies of gauges according to products.

Methods used for the analysis of the suitability of meters:

• Gauge repeatability study - Cg, Cgk
• Method of control diagrams - Cp, Cpk
• R&R study (GRR) - method based on MSA range
• R&R study (GRR) - range-based method - Bosch M3
• R&R study (GRR) - margin-based method - Non-replicable measurement
• R&R study (GRR) - a method based on the average and range of MSA
• R&R study (GRR) - ANOVA method
• Graphic analysis of meter capability
• Study of attributive gauges - cross table method
• Study of attributive gauges - short method
• Study of attributive meters - signal detection model
