Can changing master probes cause issues?

Yearly calibration tech was just in and needed to use a "service" probe, a longer probe for extra reach in their calibrations.

Now we're having issues qualifying the probes after running in house calibration.
First time only the master was checking small, so we re-ran calibration.
Now all the probes are checking the Ø of the sphere .0002"-.0004" small.

We answered Yes to 1st probe, No to the rest for the has the sphere moved question.
We have reset to theoretical box checked.
STD Dev results are looking good.

Shouldn't answering yes to has the sphere moved and resetting theo's for the master probe override any old info?
We had this issue on both CMMS.

  • Didn't look at what size the probe was in calibration results.
    This is in a qualifying program we run after calibration where we measure the sphere with all the probes and report location and sphere Ø.
    Measured a ring gage and some gage blocks and found similar range of .0002-.0004" small. Z seemed to be a little worse.
