Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display or dim display | Low or dead batteries; incorrect battery installation. | Replace batteries with new ones, ensuring correct polarity. |
| Inaccurate readings | Device placed near heat sources, vents, or in direct sunlight; sensor obstruction. | Relocate the device to a stable environment away from extreme conditions. Ensure sensors are clear. |
| Clock gains time | Internal clock drift (observed in some units). | Periodically reset the time as needed. This is a known characteristic for some units. |
| MAX/MIN values not resetting | Button not held long enough. | Ensure the MAX/MIN button is pressed and held for several seconds while MAX/MIN values are displayed. |
