Placement Systems
With performing a trend analysis we can recognize mapping errors,
e.g. as higher the y-coordinate, as higher the deviation
which trend is visible?
¾ offset increases with rising x-values (depending on the placement coordinate)
therefore required specification not achieved (C
m
-value).
Trend Analysis
Attention:
nevertheless, the average value can be in tolerance and a correction is normally not
possible by changing any software values.
