This form is used for entering and modifying the information about all available measurement devices at the enterprise.
Each device description contains:
·Device name by manufacturer
·Last proving date
·Proving interval in months
Measurement Device Database provides the following information on each selected measuring device:
The number of measuring systems, where the selected device is used,
The number of measuring operations, in which the selected device is used,
The list of measurement types for the selected device containing following characteristics:
measurement accuracy in percents
2. Device Calibration Status Database
The database on device calibration status helps to avoid various situations when particular devices are used despite its certification is over. In addition it allows for proper scheduling of new certifications.
Calibration status screen allows viewing four device lists as follows:
List of devices with valid calibration status
List of devices which need calibration within next month
List of devices which must be calibrated
List of devices which are not used
3. Measurement Systems Database
The database enables to enter, view and modify the description of measurement systems. It contains the list of the available Measurement systems. Each Measurement System contains the list of measurement operations which are made in the system.
Measurement Systems Database allows reviewing the following details for each selected measurement operation:
Metrological description of each operation
Picture or diagram or schema of the installation
Measurement device which is used for the selected operation
Type of the measurement for the selected operation.
4. System Data Monitoring
System data monitoring module allows for quick reviewing and analyzing measurement data obtained from particular operations. The module enables users to import all measurement data for each operation into the system from any .TXT type file or enter it manually. Any desirable sub-interval of the data set may be reviewed in graphics in detail. The percent of reject is shown to obtain the value of refuse.
There are two buttons which allows to get additional graphs of measurement statistics as follows:
Detailed operation analysis is available by pressing the "Data analysis" button.
Group analysis of operations by data related to the systems is available through pressing the "System analysis" button.
5. Data Analysis
This module provides users with tools for in-depth analysis of measurement data in each operation.
Data analysis screen presents the following statistical parameters:
·The exact measurement value
·Mean value of measurement series
Data analysis screen presents also the following graphs:
Distribution of measurement values
The whole measurement data processed by Spenser filter
Variation of reject in percents
Variance of measurements
6. System Analysis
This module provides users with the option of analysis of operation groups on the data sets related to the same system. Pair correlation coefficient are calculated and group analysis is performed by clicking the button "Calculate and show results".
The group analysis of obtained values along with the correlation coefficients of respective series can help to identify the reason, which may lead to obtaining poor measurement values, i.e. identify if the source of the problem is in measuring equipment or in manufacturing equipment.
MCCT offers several additional system utilities as follows:
Enterprise data back-up and restore functions
Selecting and installing additional languages
Printing the inventory labels for measurements devices
Printing the reports for review, presentations and other purposes
