The GN-BIO Single-Axis Goniometer is a device that can easily
measure the degrees of rotation around a joint. The
goniometer is composed of a stationary arm that is mounted on the part
of the body that does not move, a moveable arm that is attached to the
body part on the side of the joint that moves, and a sensor that
generates a voltage output that is proportional to the angle between
the two arms of the GN-BIO.
The GN-BIO is designed to work with the IX-BIO4, IX-BIO8 or
the IX-B3G. For other iworx recorders use the GN-100
Calibration: The GN-BIO is calibrated by
setting the GN-BIO
arm at 90 deg and at 180 degrees. The GN-BIO
Calibration template can help setting the angles.
