4.2 Outdoor Sensor Setup

1. Battery Installation: The outdoor sensor requires 3xAA batteries (not included). Open the battery compartment, insert the batteries, and close the compartment securely.
2. Assembly: Assemble the wind speed cups, wind direction vane, and rain funnel onto the sensor unit as per the diagrams in the printed manual.
3. Mounting Location: Choose an open location outdoors, free from obstructions, to ensure accurate readings for wind, rain, and temperature. The sensor should be mounted securely using the provided installation accessories. A pole or sturdy post is recommended.
4. Leveling: Use the integrated bubble level on the sensor to ensure it is perfectly horizontal. This is crucial for accurate rainfall measurement.
5. Pairing: The outdoor sensor should automatically pair with the main unit upon power-up. If pairing fails, refer to the troubleshooting section.

6. Maintenance

6.1 Sensor Cleaning

Periodically inspect the outdoor sensor for dirt, leaves, or debris, especially in the rain funnel and wind cups. Clean gently with a soft, damp cloth. Ensure the rain funnel is clear to prevent inaccurate rainfall readings.

6.2 Battery Replacement

When the low battery indicator appears on the main unit for the outdoor sensor, replace the 3xAA batteries in the outdoor sensor. Use high-quality alkaline batteries for optimal performance and longevity. Ensure proper polarity during installation.

7. Troubleshooting

• No Outdoor Data Display:
  • Check if the outdoor sensor batteries are correctly installed and not depleted.
  • Ensure the outdoor sensor is within the wireless range of the main unit (typically up to 100 meters in open air).
  • Relocate the main unit or sensor to minimize interference from electronic devices or large metal objects.
  • Try re-pairing the sensor by removing and reinserting batteries in both units, then initiating a manual search on the main unit if available.
• Inaccurate Rainfall Readings:
  • Verify the outdoor sensor is perfectly level using the bubble level.
  • Check the rain funnel for any obstructions (leaves, debris).
• Inaccurate Wind Readings:
  • Ensure the wind cups and vane rotate freely without obstruction.
  • Confirm the sensor is mounted in an open area, away from buildings or trees that could block wind flow.
• Display Not Working:
  • Check the USB power cable connection to the main unit and power source.
  • If using batteries (if applicable for main unit), ensure they are fresh and correctly installed.
