Can changing master probes cause issues?

Lake Monster
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.

  • Test some of your probe tips with a Ring/Disc gage. If the measured sizes come back correct, then the calibration is handling your compensation correctly. If it is not, go back to Hexagon with your findings.
    I've never paid much attention to the size reported for the sphere during calibration.

    Additionally, you could use gage blocks to check the Z axis comp as well, then you will have considered each direction of compensation.
