6. Maintenance
- Cleaning: Wipe the devices with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the devices in a cool, dry place away from direct sunlight and extreme temperatures. Remove batteries if storing for extended periods.
- Impeller Care (866B): Ensure the anemometer's impeller is free from dust and debris for accurate readings. Avoid touching the impeller blades directly.
- Lens Care (981C): Keep the infrared lens clean. Use a soft cloth or cotton swab with a small amount of isopropyl alcohol if necessary.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Dead or incorrectly installed batteries. | Replace batteries with new ones, ensuring correct polarity. |
| Inaccurate readings (981C). | Incorrect emissivity setting; dirty lens; distance too far. | Adjust emissivity for the target material; clean the lens; ensure proper distance (12:1 D:S ratio). |
| Impeller not spinning (866B). | Obstruction in the impeller; low wind speed. | Check for and remove any debris; ensure sufficient airflow. |
| Display is dim or blank. | Low battery power. | Replace batteries. |
