LabQuest 2

The LabQuest is capable of measuring many different quantities depending on which probe(s) is/are attached.

Temperature

1. Attach temperature probe to USB port (upper left side).

2. Turn on power (left upper side) — The unit should show temperature.

   1. Press Duration: and set to 300 s.

   2. Press Done.

   3. Press Rate: and change to 10 samples/s.

   4. Press Done.

3. Set up your experimental run with the temperature probe appropriately positioned.

4. Press to start recording the temperature. The display will change to a graph.

   Note

   On your second and subsequent runs, you will get a message about what to do with your previous run. Press Discard.

5. Allow the temperature to be recorded for about 15 s to be sure you have a flat baseline. Also, record the initial temperature in your notebook.

6. Perform a trial run.

7. After the temperature has leveled off for at least 20 s, record the final temperature, then press to stop recording.

8. Go to Step 3 for subsequent runs.
