The angle between the angle reference axis and the side of the workpiece appears as the ROTATION ANGLE in the
BASIC ROTATION function.
Cancel the basic rotation.
Restore the previous basic rotation by setting the ROTATION ANGLE to the value that you wrote down previously.
To measure the angle between two sides of a 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 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 workpiece sides appears as the ROTATION ANGLE in the BASIC ROTATION function.
Cancel the basic rotation.
Restore the previous basic rotation by setting the ROTATION ANGLE to the value that you wrote down previously.
