How Impact-O-Graph Works

The three mass-spring styluses work independently of each other, each measuring one axis- X, Y or Z. Each stylus operates by angular vibration with one degree of freedom in the direction it monitors. The mechanical , friction-free linkage from each stylus’ inertia mass converts motion from any of the three directions into the same plane and draws these forces onto the chart paper for easy reading.
