| By means of a potentiometer the galvanometer spot may be brought back to the original position. |
| Caption may be either monophonic or stereophonic, which permits the localization of the sounds source by using a directionl galvanometer. |
| Further, when the switch was opened the galvanometer was deflected in the reverse direction. |
| The galvanometer rotates mirrors to change the image that is directed from the workpiece to the camera. |
| A galvanometer in the projection system scans the screen by displaying all the columns of an image in sequence. |
| This in turn gives the galvanometer a greater readability, and by keeping the mass and inertia of the actual moving element low, a greater sensitivity. |
