Datum Setting
If you want to save the datum points in nonvolatile memory,
you must first cross over the reference marks.
Only after crossing over the reference marks can you set new datums
or activate existing ones.
There are two ways to set datums:
Touch the workpiece with the tool and then set the desired datum
(see example). You can also touch two edges and set the centerline
between them as a datum. The dimensions of the tool used for this
are automatically accounted for (see “Tool Compensation”).
Probe the workpiece with the edge finder and then set the desired
datum, or probe two edges and set the centerline as datum (see
example). The stylus radius and length are automatically accounted for
if they have been entered in parameters P25 and P26, respectively
(see “operating parameters”).
After you have set a datum, it can be activated as follows: Y
Select datum 1 or 2.
