Test control methods

1. Manual control:   the sample bending test is controlled manually, and the bending angle is   controlled manually during the bending process;

2. Automatic   control: the bending test is automatically controlled by the equipment, the   bending angle can be set, the angle is displayed from time to time during the   bending process, and it will automatically stop when the bending angle   reaches the set angle.
