Red colour vector

[[SH...]]

Nowadays I get red colour vector while scanning this is a wrong point or something wrong in my evaluation.

Red points are masked for some reason. In your case it is probably outlier elimination that masks the points.

Open up a feature, right click in the model window and you will see there is a checkmark next to show masked points. If you don't want to see the red arrows click it to remove the checkmark and it will not show them (have to close the feature and reopen it to get the updated graphics with no red arrows).

The red points are the points Calypso is eliminating per your outlier elimination setting and the default 0.3 secs that Calypso tosses at the beginning of any scan.

CMM is picking something up on the surface finish it doesnt like, and its filters are kicking in.
It could also be a sign of scanning too fast with a XXT head, do you get many "Air Scanning" errors?
Check Ruby for debris.

I've had Calypso sometimes show red masked points as green, sometimes not.

It appears the surface has some anomalies like facets all around the part and they are falling out of your outlier elimination range. Can you post a screen capture of your outlier elimination window? This looks like you might not be taking advantage of the pre-filter settings of 10 to 5000 upr, which would eliminate the negative affect of form on your outlier processing.
