6. Open a Graph display in ScienceWorkshop.

7. Start monitoring data.

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

Sensor II acquires the target.

9. You are now ready to record data.
