Finding the angle between the angle reference axis and a
workpiece edge
Select the probe function by pressing the

Select the probe function by pressing the PROBING ROT soft
key
Rotation angle: If you need the current basic rotation later, write
down the displayed rotation angle
Make a basic rotation with first workpiece edge See

page 373
Probe the second edge as for a basic rotation, but do not set
the rotation angle to zero!
Press the PROBING ROT soft key to display the angle PA
between the workpiece edges as the rotation angle
Cancel the basic rotation, or restore the previous basic rotation
