  • Digital ports on top are not used.
  • Right side has 5V power supply port.

• Power Supply and Battery Warning

  • Use the 5V power supply from the LabQuest box.
  • Plug in immediately upon return to lab to avoid data loss from battery depletion.
  • Verify connection via battery icon on screen.

• Connecting a Sensor

  • Sensor clicks in only one way.
  • Channel number appears on screen regardless of port.
  • Switch channels if probe/sensor acts irregular due to potential pin corrosion.

Experiment Setup

• Cooling Water Experiment

  • Set duration to 15 min and rate to 50.
  • Tap "Collect" to start data collection.
  • Observe freezing point behavior.

• Melting Ice Experiment

  • After cooling, melt the iced water.
  • Store data from previous run to prevent data loss.
  • Save data to USB, phone, or email.

Data Saving and Exporting

• Saving Data

  • FILE > SAVE to save in proprietary .qmbl format.
  • Requires Vernier’s Logger Pro software to open .qmbl files.

• Exporting Data

  • FILE > EXPORT to save as a .txt file for use with Excel.
