  • Qualification Problem

    Has anyone else ever seen this?

    I have a few "default" programs for everyday manual feature measurement like: Inches, Millimeters, and Calibrate.

    Each of the program names should speak for themselves I hope. Anyway, I noticed something today that I just cannot explain. The program named calibrate has always been used to do the daily tip qualifications then saved once the results are reviewed prior to going on to other programs. This is the way things have been done since I started here and I never had reason to question anything.

    Today however, I needed to change styli in the middle of the program, and so I ran a tip qualification, but, my standard deviation was huge!!!! I ran again and again, but still the same results. I ran the same tip in the "Calibrate" program and the deviations were fine. I tried the tip qualicfication in other programs and the same issue. I even created a brand new program and saw this problem. I called tech support and they told me it sounded like a settings issue. Has anyone ever seen this, and if so, what do I need to do to fix it?

    I have a feeling I am going to get into things that will require me to use autocalibrate commands in the near future, and I don't need an issue like this popping up on me.

    Any ideas would be great!

    Thanks guys,

    Make sure your probe settings are correct. To me it sounds like either your probe settings are not set to the new styli or you have it loose on your probe head.
    I used to be high on life but I built up a tolerance.

      When you "calibrate" the probes in their own program you find the sphere each time correct, then you "qualified" to the sphere within the regular probe utilities box, if this is correct then the routines are using two different sphere locations, and if you are running the "qualification" to the internal location it should show out. I hope i'm reading the thread correctly i'm only working on 1 cup of coffee right now.

        Well, another option would be are BOTH programs using the same 'tool' for the calibration? I have seen this happen, I have an 0.75, a double 0.75 and 1.50 tool for calibrations and once in a while it will pull up the 'wrong' one of the 0.75 tools for the calibration. If you use the certified size of the tool, they might be slightly different and this would cause some amount of error. Of course, this would be in the SIZE area of the probe. For the SD to be out of whack, I would look and see if the tool has been dropped and now has a flat spot.

          I think you have read the post correctly, but, to clarify further - I am using the same stylus, same qualification sphere and using the probe utilities window in each of the programs I try.

          It just happens to be that when you open the probe utilities in one program named "Calibrate" and qualify the tips, the deviations are fine, (and this will repeat) but, when you do the very same thing directly after running the first qualification in any other program the deviations are unacceptable (and these will repeat).

          I just kind of thought that I was supposed to be able to use probe utilities within any program and acheive the same results.

          I would love for it to be something like a loose probe head or something that I could see, but, I just have this feeling that it is somewhere in the settings. I just don't know where to look.

          Thanks,
          Brad

            Two more possibilities:

            1) Are you running both programs WITH the same version of Pcdmis?

            2) Were both programs MADE with the same version of Pcdmis?

              Could it be as simple as one file usings probe 2X20 and the other one is 2x20? (same/not the same), probe name with different libraries.
