Maintenance
Cleaning the Radiation Shield
The outer surface of the radiation shield should be cleaned when there is excessive dirt and
build-up on the plates. Use a damp cloth to clean the outer edge of each ring.
Note: Spraying down or using water excessively to clean the radiation shield can damage the sensitive sensors
or alter the data the sensor suite is transmitting.
Check the radiation shield for debris or insect nests at
least once a year and clean when necessary. A buildup
of material inside the shield reduces its effectiveness
and may cause inaccurate temperature and humidity
readings.
1. Using a Phillips head screwdriver, loosen the two
#6 x 2 " screws holding the five radiation shield

plates together, as shown.
2. Taking care to maintain the order in which the five
plates are assembled, separate the plates as shown
and remove all debris from inside the shield.
3. Reassemble the plates in the same order in which
they were disassembled, and fasten them together
using a Phillips head screwdriver to tighten the
#6 x 2 " screws, as shown.

Cleaning the Rain Collector, Debris Screen, and Tipping Spoon Module
To maintain accuracy, thoroughly clean the rain collector cone and debris screen as needed or
at least once a year.
Note: Cleaning the rain collector and tipping spoon may cause false rain readings. See "Clearing Data Col-
lected During Testing and Installation" on page 10.
1. Use a damp, soft cloth to remove any debris from the rain collector and debris screen.
2. Use pipe cleaners to clear any debris remaining in the screen.
3. When all parts are clean, rinse with clear water.
