Turning on the Sensors: [User Manual, page 5]. Place a magnet next to the end of the sensor near the LED window. The LED light will turn on and after 3-4 seconds will begin blinking rapidly. Once blinking rapidly, move the magnet away and the LED will blink more slowly, about two to three times per second. Repeat with all sensors. They are then ready to connect to the Lameness Locator® program.
Instrumenting the Horse: [User Manual, page 9-13].
Head Sensor: Attach either to felt head bumper or directly to halter. The LED should face the horse’s right side.
Right Forelimb Sensor: Attach to dorsal aspect of the right forelimb pastern using the pastern wrap. Sensor label should face away from the limb and the LED should face medially.
Pelvic Sensor: Attach to a strip of 3M Dual Lock tape placed between the tubera sacrale on the midline of the pelvis. The LED should face the horse’s right side.
