The angle between the angle reference axis and the side of the
workpiece appears as the ROTATION ANGLE.
Cancel the basic rotation.
To restore the previous basic rotation:
Set the ROTATION ANGLE to the value that you wrote down previously.
To measure the angle between two sides of a workpiece:
Select the probe function with the PROBING ROT soft key.
ROTATION ANGLE
If you will need the current basic rotation later, write down the value that
appears under ROTATION ANGLE.
Make a basic rotation for the first side (see “Compensating workpiece misalignment”).
Probe the second side as for a basic rotation, but do not set the ROTATION ANGLE to zero!
The angle PA between the two sides appears under ROTATION
ANGLE.
Cancel the basic rotation.
To restore the previous basic rotation:
Set the ROTATION ANGLE to the value that you wrote down previously.
