Care and Maintenance
Do not wrap the cable tightly around the sensor for storage. Repeatedly doing so
can irreparably damage the wires and is not covered under warranty.
How the Sensor Works
The flexible arm of the Goniometer is attached to a metal dialon the sensor head
that can rotate 360º. A magnet inside the sensor rotates with this dial. A magnetic
encoder is used to report the position of the magnet. As the magnet rotates, the
encoder produces a voltage that is converted into the position (angle) of the dial by
the data-collection software.
