SP25 calibration issue

Please note that this thread is not in the OFF TOPICS section, so only clever answers are welcome !!!

I greet you all, colleagues.
I have a small problem that tends to come and go when calibrating angles. I work with many styli and use a 9-slot magazine for this. Each stylus has about 10 different angle positions. When I did the calibration, two angles on different probes were out of tolerance. One probe has a CM25-2 probe and the other CM25-3. And at the same time, PSDMIS accepts the calibration result without asking the operator. The next day I did a similar calibration and the result was OK.And always out-of-tolerance angles equal to A90 or more than A90 It is very strange . I have been working in this mode for 3 years and there were no such problems. And this year it started. I check the probes visually and do the cleaning before each calibration the same way always. What could be the problem ?

  • If using an 'L' tip or a starcluster it appears that the tip itself may not be squared to an axis. But Chris has a very comprehensive list of items to help.
    Try partial calibration instead of the full scan calibration, see if your results change significantly. While performing partial calibration you can utilize the 'user defined' area of calibration mode to ensure the probe isn't able to 'accidentally' touch the stem of your qualification sphere.

    Last thing I think you could have is an incorrect component selected in your probe builds. The selection is close enough for you to utilize but could be why you see deviations that appear so drastic.
  • Thank you very much, I will take your recommendation to check how I assembled the dipstick
