Note: When the ScienceWorkshop program is set to monitor or record data, the Motion Sensor II transducer will be triggered to produce the ultrasonic pulses that are used by ScienceWorkshop to determine the location of the target. 8. Adjust the angle of the transducer, the Narrow/Std. mode, and the trigger rate as necessary to achieve the optimal signal. Note: The LED will light when the Motion Se
