- Inbutua: Collects rainwater.
- Tipping Bucket Mechanism: Measures rainfall in precise increments.
- Haririk gabeko igorlea: Sends data to the display unit (max. 100m range).
- Bateriaren konpartimendua: For batteries (usually in the base of the collector, though not explicitly stated for this unit, it's standard).
5. Konfigurazioa
5.1. Bateriaren instalazioa
- Display Base Unit: Open the battery compartment on the back of the display unit. Insert 4x 1.5V AA batteries, observing the correct polarity (+/-). Close the compartment.
- Euri-biltzailea: Open the battery compartment on the rain collector. Insert 4x 1.5V AA batteries, observing the correct polarity (+/-). Close the compartment securely to ensure weather resistance.
Note: It is recommended to insert batteries into the rain collector first, then the display unit, to facilitate immediate pairing.
5.2. Placement of Units
- Euri-biltzailea:
- Place the rain collector in an open area, away from trees, buildings, or other obstructions that could block rainfall or create false readings.
- Ensure it is level to guarantee accurate measurements. A mounting bracket (not included, but typically available) can be used for secure installation on a pole or fence.
- The maximum wireless transmission range is 100 meters (328 feet) in open air. Obstacles like walls and electronic interference can reduce this range.
- Display Base Unit:
- Place the display unit indoors, within the wireless range of the rain collector.
- Avoid placing it near large metal objects, electronic devices, or sources of strong electromagnetic interference.
5.3. Hasierako sinkronizazioa
Once batteries are installed in both units, they should automatically attempt to synchronize. The display unit will show a signal strength indicator. If synchronization fails, refer to the Troubleshooting section.
6. Funtzionamendu-argibideak
