1. Clean the rain gauge once every 3 months as follows. Reference Figure 34.

Step 1: Make a note of the current rain totals by referencing the calibration screen (reference

Section 6.5). You will need to re-enter these values after the calibration procedure it complete.

Step 2: Pour water into the rain collector to moisturize the dirt inside rain bucket.

the mechanism no longer rotates.

Step 4: Rotate the cotton swab back and forth, removing dirt from the tipping mechanism and

9.1 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 35.

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 36.
