Maintenance; Advanced Rain Gauge Cleaning - Aercus WeatherSleuth Mode D'emploi

6. Maintenance

1. Clean the rain gauge once every 3 months as follows. Reference Figure 31.
Step 1: Make a note of the current rain totals by referencing the calibration screen (reference
Section 3.6.9). You will need to re-enter these values after the calibration procedure it
complete.
Step 2: Pour water into the rain collector to moisturise the dirt inside the rain bucket.
Step 3: Use an approximately 80mm long cotton swab, and push the cotton tip through
the rain collector hole until it reaches the self-emptying mechanism, and press until the
mechanism no longer rotates.
Step 4: Rotate the cotton swab back and forth, removing dirt from the tipping mechanism and
rain collector hole.
Step 5: Remove the cotton swab and flush with water to remove any remaining dirt.
Step 6: Re-enter the rain totals recorded in Step 1.
2. Clean the solar radiation sensor every 3 months with water and towel.
3. Replace batteries every 12 months or when signal reception deteriorates.

6.1 Advanced Rain Gauge Cleaning

If the rain gauge stops updating, it is possible for spiders and other insects to nest inside the sensor
array housing and interfere with the rain gauge mechanism.
1. Remove the six screws on the bottom of the sensor array, as shown in Figure 32.
2. CAREFULLY separate the top housing from the bottom housing. They cannot be completely
separated due to wires. DO NOT STRESS THE WIRES. Open the sensor housing slightly,
like a clam shell.
3. Clean any debris and spider webs, as shown in Figure 33.
