8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not turn on | Low or dead batteries; Incorrect battery polarity. | Replace batteries; Check battery orientation. |
| Inaccurate measurements | Unstable surface; Obstruction in laser path; Incorrect reference point; Extreme temperature changes. | Ensure stable measurement; Clear laser path; Verify reference point setting; Allow device to acclimate to temperature. |
| Laser beam not visible outdoors | Bright ambient light. | The green laser is brighter than red, but direct sunlight can still affect visibility. Use a target plate or measure in shaded areas if possible. |
| Display shows "Error" | Measurement out of range; Laser signal too weak or too strong. | Ensure target is within 328ft range; Measure on a suitable surface; Clean laser lens. |
