Step 4c
n Position B = -90
n Probe surface Z
n Set Z = 0
n Position B = +90
n Probe surface Z
n MP7530.6 = –0.5 * determined value – MP7530.1
Step 5
n Probe surfaces X1, X2, Y2 and Z in a tilted working plane with the tilting angles B = –90, B = +90
and C = 180 (with MP7500 = %xxxxx0x)
n If there are differences between the individual tilting angles, the offsets from MP7530.0 and
MP7530.3 should be determined with a different process (steps 6 to 8), and the averages from both
processes should be entered in MP7530.0 and MP7530.3.
Step 6
n Probe surface Y2
n Set Y = 0
