Troubleshooting
If you encounter issues with your AP-816B anemometer, refer to the following common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low or dead battery; Incorrect battery installation. | Replace the CR2032 battery. Ensure the battery is inserted with the correct polarity (+ side up). |
| Inaccurate wind speed readings. | Fan wheel obstructed; Device not positioned correctly in wind flow. | Check the fan wheel for any obstructions (dust, debris) and clean if necessary. Ensure the fan is directly facing the wind. |
| Inaccurate temperature readings. | Temperature sensor obstructed or exposed to direct heat/cold source. | Ensure the temperature sensor area is clear. Allow the device to stabilize in the environment for a few minutes before taking readings. Avoid direct sunlight or extreme heat/cold sources. |
| Display is dim or flickering. | Low battery. | Replace the CR2032 battery. |
