How to change the sphere reference in probing system qualification?

[[AD...]]

this morning, i ran the master probe and the someone change the sphere reference 30mm to 8mm for calibration. after that, i change back the the sphere reference 30mm and start calibrate the master probe. After finish calibration, suddenly sphere reference automatically change back to 8mm calibration. and i start run the auto calibration program and another probe hitting the calibration ball.

If you had the wrong reference ball selected when locating the sphere, your master probe will have the wrong length and diameter and will have to be manually corrected.

i already select the right reference ball after calibration still change from reference sphere 1 to sphere 2
