You are ready to continue your experiment.

Connect Your Sensor Using Wi-Fi and LabQuest 3

Data Sharing lets you stream data collected on a LabQuest 3 (or LabQuest 2) to multiple devices that are running Graphical Analysis. Your LabQuest must be on the same Wi-Fi network as your devices.

1. Connect the sensor to your LabQuest.
2. Enable Data Sharing on LabQuest.
3. Launch Graphical Analysis on your computer.
4. Click or tap 
5. Choose your LabQuest from the list of discovered Data Sharing sources.
   • If your version of Graphical Analysis has the Pro features unlocked, select the Local data sharing option to see the list of devices.
   • If your LabQuest does not show up in the list, click or tap  and enter the IP address of the LabQuest.
6. Graphical Analysis will connect to LabQuest.

You are ready to continue your experiment. When you begin data collection on LabQuest, the data will appear on your computer.
