How to troubleshoot Apogee Quantum sensor not responding?
- SScott CastanedaJul 28, 2025
If your Apogee Measuring Instruments sensor isn't responding, check the power to both the sensor and the logger. Inspect the sensor cable and stereo plug connector for any damage. Ensure that the sensor's SDI-12 address is set to 0, which is the factory default. You can verify this using ZENTRA Utility by navigating to Actions, selecting Digital sensor terminal, choosing the correct port, and sending the ?I! command to the sensor from the dropdown menu.
