1 .
Probe the workpiece.
The value displayed as DATUM is the distance between the two points on
the coordinate axis.
To return to the datum that was active before the length measurement:
Select the SURFACE = DATUM probe function.
Probe the first touch point again.
Set the datum to the value that you wrote down previously.
Terminate the dialog.
Measuring angles
You can also use the 3D touch probe system to measure angles in the
working plane. You can measure
• the angle between the angle reference axis and a workpiece side, or
• the angle between two sides.
The measured angle is displayed as a value of maximum 90°.
To find the angle between the angle reference axis and a side of the workpiece:
Select the BASIC ROTATION probe function.
ROTATION ANGLE =
If you will need the current basic rotation later, write down the value that appears under ROTATION ANGLE.
Make a basic rotation with the side of the workpiece (see “Compensating workpiece misalignment”).
