Evaluation Criteria - HBM MP85A Series Operating Manual

Measurement procedure
Fig. 8.8 shows two measured curves: On the left, measured curve 1 with a
mean value in the upper section of window 2; on the right, measured curve 2
with a mean value in the center of window 2. This means that window 3 is also
shifted down as compared with the graph on the left.

Evaluation criteria

The MP85A process controller has different window types to allow the univer­
sal evaluation of different curve shapes using the window method. These win­
dow types can be mixed as desired for each measured curve. If you wish to
monitor the entire process seamlessly, an envelope curve is available.

Thread-in window
Checks that the fitting partners thread in correctly and are not askew.
A real-time signal indicates a thread-in problem (e.g. the window is exited from
the top). Use this for press control, e.g. for initiating the press return stroke.
