you can also use all the previously described manual touch probe

functions (exception: calibration function) with mechanical probes

or by simply touching the workpiece with the tool.
In place of the electronic signal generated automatically by a

3-D touch probe during probing, you can manually initiate the

trigger signal for capturing the
