Three mass-spring styluses work independently of each other, each measuring one axis - X, Y and 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.
Recorders are delivered ready to use with paper and battery already installed (no ink is used). An Operations Manual is provided with each recorder.
1. Mount the Impact Recorder securely to the object to be monitored.
2. Remove the stylus guard and set the chart paper to the starting time.
3. Turn the recorder on. Lock the cover if desired.
The recorder is ready to document impacts on pressure sensitive paper.
The three bracket styli can be ordered with the same or different G-levels, for example: 2x, 15y, 6z. The appropriate G-level will depend on several factors, including product sensitivities, mode of transport and packaging.
