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.
To clean the tipping spoon assembly, it must first be removed from the ISS base.
