Master probe tips
Teaching a probe also establishes the spatial (X, Y, and Z) position of the probe
tip (master probe tip) or the X, Y, and Z offsets (non-master tips) from the
master tip. There is only one master tip for multi-sensor systems. All tips are
referenced to the master tip regardless of group. The X, Y, and Z values of each
probe in a group is compared to the master probe. The difference becomes the
X, Y, and Z offset value for each non-master probe tip.
For example, a star probe group has five probe tips: one master tip and four
non-master tips. The X, Y, and Z position on the non-master tips are all calcu-
lated by the offset from the position of the master tip. Since the tips on a star
probe are fixed and repeatable simply re-teaching the master tip is sufficient to
update the entire group.
The same holds true for index probes. Each position can be entered into probe
library as a new tip. Establishing one position as the master tip allows all the
non-master tips (positions) to update when the master tip is re-taught.
To teach (qualify) a master probe tip
Step 1
Highlight the desired probe as shown.
Step 2
Check the reference offset checkbox as shown.
