Using the Lab Cradle with a Handheld You can connect the Lab Cradle to your handheld to collect or retrieve data. Using the Lab Cradle with a Computer The Lab Cradle works with all Windows® and Mac® operating systems currently supported by the TI-Nspire™ Teacher and Student computer software. Using the Lab Cradle as a Stand-Alone Data Collection Tool You can use the Lab Cradle in stand-alone mode to collect data either manually or automatically. Press the trigger button to manually start and stop data collection when in stand-alone mode. Note: For long-term data collections TI recommends you use an AC adapter for a handheld or a remote collection device such as the Lab Cradle. Before collecting data, set up the data collection parameters using the Vernier DataQuest™ app or use the sensor's default settings. If you do not change the parameters and use a single sensor, the Lab Cradle collects data using the sensor's default settings. If you use multiple sensors, the Lab Cradle collects samples beginning with the sensor that has the shortest collection time requirement. You do not have to reconnect the Lab Cradle to the same computer or handheld to download the data. You can use any computer or handheld running a compatible OS and TI-Nspire™ software to download the data. Learning About the Lab Cradle Portability The Lab Cradle fits into the palm of most high school students' hands when connected to the TI-Nspire™ handheld. The Lab Cradle features an attachment point for a lanyard. Students can attach a lanyard to wear the Lab Cradle around their neck. This feature lets students keep their hands free to steady themselves in rough terrain during remote data collection activities. When collecting data for an experiment that subjects the Lab Cradle to intense movement, TI recommends that students wear a Vernier Data Vest or zip-up jacket with the sensor secured both around the student's neck as well as to the student's chest. For example, if a student is measuring speed or motion on a roller coaster, the Lab Cradle may bounce around due to the movement of the roller coaster. Wearing a zip-up jacket or Vernier Data Vest limits the movement of the Lab Cradle. 92 TI-Nspire™ Lab Cradle
