The display base unit features a clear LCD screen that shows various rainfall measurements, indoor temperature, time, and date. It also has buttons for navigation and settings.

• LCD Display: Shows current, hourly, daily, weekly, monthly, and total rainfall, indoor temperature, time, and date.
• Control Buttons: For setting time, date, alarm, and viewing historical data.
• Battery Compartment: Located at the back, for 4x AA batteries.

4.2. Wireless Rain Collector (Pluviometer)

The rain collector is a self-emptying, frost-resistant outdoor unit that measures rainfall and wirelessly transmits the data to the display base unit.

• Funnel: Collects rainwater.
• Tipping Bucket Mechanism: Measures rainfall in precise increments.
• Wireless Transmitter: Sends data to the display unit (max. 100m range).
• Battery Compartment: For batteries (usually in the base of the collector, though not explicitly stated for this unit, it's standard).

5. Setup

5.1. Battery Installation

1. 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.
2. Rain Collector: 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

• Rain Collector:
  • 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. Initial Synchronization

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. Operating Instructions

6.1. Setting Time and Date

Refer to the specific buttons on your display unit (e.g., "SET", "MODE", "UP", "DOWN") to adjust the time and date. Typically, you press a "SET" button to enter setting mode, then use "UP/DOWN" to change values and "SET" or "MODE" to confirm and move to the next setting.

6.2. Viewing Rainfall Data

The display unit provides various rainfall measurements:

• Current Rainfall: Real-time measurement.
• Last Hour: Rainfall accumulated in the past 60 minutes.
• Last 24 Hours: Total rainfall over the last day.
• Last 7 Days: Total rainfall over the past week.
• Current Month: Total rainfall for the current calendar month.
• Current Year: Total rainfall for the current calendar year.
• Total Rainfall: Cumulative rainfall since the device was last reset.

Use the designated buttons (e.g., "HISTORY", "MODE") to cycle through these different display modes.

6.3. Monthly History Function

The device stores monthly rainfall data for the last 12 months. Access this feature via the display unit's buttons to review past rainfall trends.

6.4. 24-Hour Rain Alarm

You can set a 24-hour rain alarm to be notified when a certain amount of rainfall has been reached within a 24-hour period. Consult your display unit's manual section for setting this alarm threshold.

6.5. Indoor Temperature Display

The display base unit also shows the indoor temperature, typically in Celsius or Fahrenheit. You may be able to switch between units using a dedicated button or setting.

7. Maintenance

7.1. Cleaning

• Rain Collector: Periodically check the rain collector's funnel for debris (leaves, dirt, insects) that could obstruct the tipping bucket mechanism. Clean gently with a soft cloth and water. Do not use abrasive cleaners.
• Display Unit: Wipe the display unit with a soft, dry cloth. Avoid using liquid cleaners.

7.2. Battery Replacement

When the battery indicator appears on the display unit, replace all batteries in both the display unit and the rain collector simultaneously. Use fresh 1.5V AA batteries. Follow the battery installation steps in Section 5.1.

7.3. Frost Resistance

The rain collector is designed to be frost-resistant. However, in extremely harsh winter conditions, it is advisable to bring the outdoor unit indoors to prevent potential damage and prolong its lifespan.
