Measuring angles
You can also use the probing electrode 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
8
Select the probing function by pressing the PROBING
ROT soft key.
8
Rotation angle: If you will need the current basic
rotation later, write down the value that appears
under Rotation angle.
8
Make a basic rotation with the side of the workpiece
(see ”Compensating workpiece misalignment” on
page 27).
8
Press the PROBING ROT soft key to display the angle
between the angle reference axis and the edge of the
workpiece as the rotation angle.
8
Cancel the basic rotation, or restore the previous basic
rotation by setting the Rotation angle to the value that
you wrote down previously.
To measure the angle between two workpiece sides:
8
Select the probing function by pressing the PROBING ROT soft key.
8
Rotation angle: If you will need the current basic rotation later, write
down the value that appears under Rotation angle.
8
Make a basic rotation with the side of the workpiece (see
”Compensating workpiece misalignment” on page 27).
8
Probe the second side as for a basic rotation, but do not set the
Rotation angle to zero!
8
Press the PROBING ROT soft key to display the angle PA between
the two sides as the Rotation angle.
8
Cancel the basic rotation, or restore the previous basic rotation by
setting the Rotation angle to the value that you wrote down
previously.
