Simply select the ratio of reduction or enlargement, connect the clamp to the board and pantograph, and use the trace point to trace over the original drawing.

How does the pantograph work and how is it able to produce an enlarged image?

It’s based on parallelograms so that when moving one specified point, called the tracing stylus, along the outline of an image, an enlarged or reduced version of the image is created by the movement of another point, called the drawing stylus, which has a lead affixed to it.
