Model No. PS-2138 Goniometer 3 ® Goniometer PS-2137, PS-2138 Model PS-2137 includes probe, straps and angle sensor; model PS-2138 includes probe and straps only. Introduction With the PASPORT Goniometer students can analyze motions such as walking, running, throwing and kicking. They can also explore the physics of rotational dynamics using their arms and legs as experimental apparatus. The Goniometer, in conjunction with a PASPORT interface, measures and records the angle, angular velocity and angular acceleration of an elbow, knee or hip. The sensor can be used with a single Goniometer Equipment Included Part Number Probe PS-2138 Mounting straps (two small, one large) PS-2547 Angle Sensor (included in PS-2137 only) PS-2139 ANGLE 12 PS-2139 ä SENSOR Probe Angle Sensor Required or Optional Equipment PASPORT Interface (required) See PASCO catalog or www.pasco.com Second Goniometer Probe (optional) PS-2138 Mounting Straps

Goniometer Probe Mounting 4 ® Probe (included) or with an optional second probe to measure two joints simultaneously. You can use multiple sensors together to support even more probes. The probe is easily attached to the body using the included hook-and-loop mounting straps. The Goniometer Probe consists of two arms and a potentiometer. As the angle between the arms changes, the resistance of the potentiometer changes. The Angle Sensor, connected to the probe, measures the resistance of the potentiometer and converts it to an angle measurement. The sensor also calculates the angular velocity and angular acceleration from the rate at which the angle changes. The data is sent digitally to your PASPORT interface at up to 100 samples per second. The probe measures zero degrees (or radians) when it is fully open. A clockwise rotation of the narrow arm relative to the wide arm (as pictured) is measured as increasing angle. Probe Mounting The mounting straps can be used in two ways. The easier method is to place the straps on the limbs, then stick the probe to the outside of the straps. For more secure attachment, tuck the probe arms inside the overlapping portions of the straps. When mounting the Goniometer probe, the wide and narrow arms of the probe are interchangeable; the only difference will be the sign of the data collected. Attach the wide arm of the probe to the subject’s upper arm when used on the left elbow, and to the subject’s forearm when used on the right elbow. This will result in a flexion of either joint measured as a positive displacement. Similar reversals can be applied to knee and hip mounting.
