The Digiforce 9307 monitors processes in which precisely defined functional relationships between two or more measured quantities need to be demonstrated. These quantities are recorded synchronously during a manufacturing process or functional testing to produce a measurement curve, which is then assessed using graphical and mathematical evaluation techniques. After internal evaluation, the curve and evaluation results are visualized on a color display and are also output via external control interfaces. The processes in the controller are optimized by a powerful real-time operating system to achieve a fast evaluation cycle: It typically takes just 15 milliseconds to deliver an “OK” or “not OK” result, which can then be analyzed by a higher-level controller.
In addition to traditional evaluation windows with defined entry and exit sides, the instrument also offers thresholds, trapeziums of type X or Y, and envelopes as graphical evaluation elements. Individual evaluation results from the graphical tools can then be combined by mathematical operations to provide even more analysis flexibility for a range of signal curves.
