MT - OASYS®
Statistics Module
|
High-precision analysis of test data is undertaken by the OASYS®
Statistics Module.
|
|
Example:
Statistical analysis of 5 yarn specimens in summary form. The
individual diagrams may also be retrieved in full-page format.
|
|
The Classifications Matrix |
comes as standard equipment with our system. This
matrix classifies all defects in respect to their length and their
variation in diameter. This is very useful for classifying and
defining major yarn defects. Settings can be modified before each
test is carried out. |
| The IPI-Values |
are indicated by the colour zones and
record the neps, thick and thin places per km. |
|
A Reference Diameter |
is established in the first 100 m. This reference
value is used as a basis for all statistical comparisons in the
classification matrix and IPI-values.
On the right adjacent to the matrix, the statistical means for the
yarn are shown: neps, thick places, thin places, OCV index
and reference value. |
| The Histogram |
shows the diameter distribution (frequency
distribution) in the yarn. You can choose between a line diagram
display and 3-D bar chart. |
| The Spectrogram |
shows the periodic defects in the yarn. A “tower”
indicates that this defect occurs with relatively strict
periodicity. This diagram shows the frequency distribution of the
wavelengths that occur. |
| The CVL-Curve |
represents the variation length
coefficient in a diagram. |
|
The Optical CV%-
Index (OCV%) |
shows the amount of “true” irregularity of a yarn
and can not be compared to the capacity method.
Amongst the reasons for this incompatibility are:
-
different principles of measurement
(optical – determination of diameter, capacitive – determination
of mass variations)
-
different test zone lengths (integration
stages), capacity method 8 mm, optical (OASYS®) method 2 mm
-
different methods of correlation (Zweigle OASYS®
absolute, capacity relative)
|
|
Statistical Comparisons |
allow you to undertake various tasks such as diagram
overlays for displaying several tests in a single diagram. |
