General Troubleshooting steps:

  1. Make sure the interface has power. For trouble shooting purposes, remove the batteries from LabPro. A few seconds after connecting LabPro to AC power, it should make the “happy sound” to indicate that it has power and has passed a self-test.


Download the MP3, or WAV file.

If the LabPro does not make the “happy sound”, see
LabPro gives unfamiliar beeps or does not make the "happy sound."

  1. Check all of your cable connections. Make sure that one end of the cable is completely plugged in to the interface and the other end is all the way into the computer.
  1. What version of Logger Pro are using? To find out, open the program and choose “About Logger Pro“. The exact version number will be at the bottom of the window that opens. Many problems can be resolved by installing a free upgrade from our web site. If Logger Pro was installed via a push or image process from the school IT department, there is chance the software drivers are not installed correctly.

Are the device drivers installed correctly? (For Windows with LabPro, original LabQuests, LabQuest Mini, and LabQuest Stream)

  1. If you have multiple computers and interfaces, with some of them are working and some are not, try methodically switching interfaces, cables, power supplies and computers to see if the problem is with a piece of the hardware.
