| Symptom | Probable Cause | Advanced Solution | | :--- | :--- | :--- | | | Sensor short circuit | Unplug probe. Measure resistance between pins. Should be 10kΩ @ 25°C. If 0Ω, replace. | | Unable to enter CFG mode | Battery voltage > 3.0V (new batteries) | Briefly short battery contacts with a resistor (100Ω for 0.5 sec) to drop voltage, or use USB power only. | | USB not recognized | File system corrupted | Do not format. Use chkdsk /f on the drive letter in CMD. Then use "Eject" every time. | | Alarm sounds randomly at 3 AM | Minimum temperature violation | Check Parameter P03 (Low Trip) vs. overnight ambient drift. Increase deadband (P04). | | Log file shows "---" | Logging paused due to memory full | Change P25 to "Stop When Full" and download data before re-use. |
