Gradcal will not converge.
Symptom
Gradcal will not converge. Applying recommended corrections causes major changes in calibration results FE is running Gradcal on a new installation. He's using the Automated Gradcal Tool from the Service Desktop, but the same thing happens in manual mode also. The phantom measurements are fairly close to nominal, but they are out of spec and need touching up. The program applies corrections to the xfull, yfull, and zfull values that are too large, causing swings that are too far into the wrong direction. The FE checked the phantom position in all three planes and found it to be correct.
