4. Setup and Installation
4.1 Battery Installation
Display Unit:
- Open the battery compartment cover on the back of the display unit.
- Insert the required batteries (e.g., 3 x AAA, not included) according to the polarity markings (+/-).
- Close the battery compartment cover.
Rain Collector Sensor (Outdoor Unit):
- Locate the battery compartment on the outdoor rain collector. This may require unscrewing a cover.
- Insert the required batteries (e.g., 2 x AA, not included) according to the polarity markings.
- Securely close the battery compartment to ensure water resistance.
4.2 Sensor Placement
Proper placement of the rain collector sensor is crucial for accurate readings:
- Choose an open area where the sensor will not be obstructed by trees, buildings, or other structures that could block rainfall or cause runoff.
- Ensure the sensor is level to guarantee accurate measurement. Use a spirit level if necessary.
- Mount the sensor securely using the provided mounting bracket and screws. It should be high enough to avoid splashing from the ground but accessible for maintenance.
- Place the display unit indoors, away from direct sunlight and heat sources, and within the wireless range of the outdoor sensor (typically up to 100 meters in open air).
4.3 Initial Setup and Pairing
After battery installation, the display unit will attempt to connect with the outdoor sensor. This may take a few minutes.
- Ensure both units are powered on and within range.
- The display unit should automatically detect the outdoor sensor and begin displaying outdoor temperature and rainfall data.
- If pairing fails, try resetting both units (remove and reinsert batteries) and place them closer together during the initial pairing process.
Time and Date Setting:
The unit features WWVB radio-controlled time. Once connected, it will attempt to synchronize the time automatically. If manual adjustment is needed:
- Press and hold the "MODE/SET" button to enter time setting mode.
- Use the "UP/HIST" and "DOWN/MEM" buttons to adjust values.
- Press "MODE/SET" again to confirm and move to the next setting (e.g., 12/24 hour format, time zone, date).
5. Operating Instructions
5.1 Display Overview
The display unit provides a clear overview of all monitored data:
- Time and Date: Located at the top, showing current time, day, and month.
- Rainfall Data: Displays current rainfall (e.g., "35.9 mm" as seen in the image) and a "Historical histogram" showing rainfall over different periods (Day, Week, Month).
- Indoor Temperature: Labeled "IN", showing the temperature measured by the display unit itself (e.g., "23.4°C").
- Outdoor Temperature: Labeled "OUT", showing the temperature from the remote sensor (e.g., "30.9°C").
- Signal Strength: An icon indicating the wireless connection strength between the display unit and the outdoor sensor.
- Alert Indicators: Icons for alarms or rain alerts.
5.2 Button Functions
| Button | Function (Short Press) | Function (Press and Hold) |
|---|---|---|
| MODE/SET | Toggle display modes (e.g., time, alarm). | Enter setting mode for time, date, alarm. |
| UP/HIST | Increase value in setting mode; View historical rainfall data. | Activate/deactivate certain functions (refer to specific modes). |
| DOWN/MEM | Decrease value in setting mode; View minimum/maximum temperature records. | Clear minimum/maximum records. |
| RAIN ALERT | Activate/deactivate rain alarm. | Set rain alarm threshold. |
5.3 Viewing Historical Rainfall Data
To view historical rainfall data, repeatedly press the "UP/HIST" button. The display will cycle through different time periods (e.g., daily, weekly, monthly) and show the corresponding rainfall amounts and the histogram.
5.4 Setting Rain Alert
The rain alert function notifies you when a certain amount of rainfall has been collected.
- Press and hold the "RAIN ALERT" button until the alert threshold starts flashing.
- Use "UP/HIST" or "DOWN/MEM" to adjust the desired rainfall threshold.
- Press "RAIN ALERT" again to confirm the setting.
- A short press of "RAIN ALERT" will toggle the alarm on or off.
6. Maintenance
- Cleaning the Rain Collector: Periodically check the rain collector for debris such as leaves, twigs, or insects that could obstruct the tipping bucket mechanism. Clean with a soft, damp cloth. Do not use abrasive cleaners.
- Battery Replacement: Replace batteries in both the display unit and the outdoor sensor when the low battery indicator appears on the display. Use fresh batteries of the specified type.
- Winter Care: While the product is described as "Freeze Proof Rainfall Measurer", it is generally recommended to bring the outdoor sensor indoors during extreme freezing conditions to prolong its lifespan and prevent potential damage from ice buildup.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No outdoor temperature/rainfall data on display. | No wireless connection; Batteries low/dead; Sensor too far or obstructed. | Check batteries in both units. Move display unit closer to sensor. Remove obstructions. Re-pair units by resetting both. |
| Inaccurate rainfall readings. | Rain collector not level; Debris in collector; Sensor obstructed. | Ensure collector is level. Clean out any debris. Relocate sensor to an open area. |
| Display is blank or dim. | Low or dead batteries in display unit. | Replace batteries in the display unit. |
| Time is incorrect. | WWVB signal weak or unavailable; Manual setting needed. | Relocate display unit near a window for better signal. Manually set time if automatic synchronization fails. |
