Why doesn't my LabQuest unit recognize auto-ID sensors?

Not all sensors are auto-ID capable. If you have older sensors with round DIN plugs and adapters, they are incapable of auto-ID. Some other sensors, such as older radiation monitors and drop counters, are also not auto-ID. You must manually set them up by choosing Sensor Setup from the Sensors menu.

If you have auto-ID sensors connected and they are not recognized, try cycling the power by holding the power button down for three seconds, waiting until the power LED turns off, then pressing the power button to turn the unit back on. If cycling power does not work, try rebooting the LabQuest. See TIL 1777: How do I reboot or reset a LabQuest?

If that does not work, try this:
1. From the Meter screen, choose Sensor Setup from the Sensors menu.
2. Are the channels are listed (CH1, CH2, etc.)? If you see "no devices found" or the only thing listed is "Internal Microphone", the LabQuest may need to be repaired. Please contact Vernier Tech Support for further troubleshooting.
