User Interface of the WinFTM Software Measurement Value Field
If you have set up tolerance limits, the measurement value is displayed with colored back-
ground. If the measurement value is within the tolerance limits, the measurement value is
displayed on green background, otherwise on red background.
6.4.3 SPC Chart Presentation
In this display mode the SPC chart (Statistical Process Control chart) is displayed in the
statistics field. The measurement values are displayed in the list presentation in the
measurement value field.
Within the statistical process control chart you can identify trends in automated measuring
procedures with large lot sizes. Thus, you can easily determine changes with regard to
coating thickness and other process parameters. Furthermore, the SPC chart presentation
simplifies the monitoring of the measurement devices.
