Auto Calibration Issues

Hi All,

I am currently attempting to roll out Auto Cal at the start of all of our programs to save time calibrating probes - we used to auto calibrate over a weekend (would take around 40hrs to fully calibrate) but we found that after a few days we would see issues coming from our measurements (error varied between 0.005 up to 0.15) - all measurements where manually verified and then re-calibrated and re-measured and wold then come in and agree with the manual check.

Please see below a snippet of how our autocal works currently

 

C9         =COMMENT/YESNO,NO,FULL SCREEN=NO,AUTO-CONTINUE=NO,OVC=NO,
            Do Probes Require Calibration?
            IF_GOTO/C9.INPUT=="YES",GOTO = PROBES
            GOTO/SKIP_PROBES
PROBES     =LABEL/
            LOADPROBE/LEITZ TREE 01 1X50 P&P
            TIP/T1A0B0, SHANKIJK=0, 0, 1, ANGLE=0
            AUTOCALIBRATE/PROBE, PARAMETER_SET=AUTO_CAL, QUALTOOL_MOVED=NO, 
                          CHECK COLLISION=NO, SHOW_SUMMARY=NO, OVERWRITE_RESULTSFILE=NO
            GOTO/SKIP_PROBES

The issue we are seeing is that with this they seem to autocalibrate over eachother overwriting results (overwrite is turned off and results file is not updated) however if we do a manual calibration then the results come into real life values as oer manual checks

does anyone have any suggestions or any help as to why this could be happening.
