Troubleshooting: Cleaning the Radiation Shield

17

Cleaning the Radiation Shield

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 will reduce its 
effectiveness and may cause inaccurate 
temperature and humidity readings.

To clean the radiation shield:

1. 

Remove the rain collector cone.

2.

Using a Phillips head screwdriver, loosen the 
three 4” (~100mm) bolts holding the radiation 
shield plates together.

3.

Separate the plates as shown and remove all 
debris from inside the shield.

4.

Reassemble the radiation shield plates and fas-
ten them together using the bolts as shown in 
the illustration. Use a Phillips screwdriver to 
tighten the bolts. 

Cleaning the Rain Collector

To maintain accuracy, thoroughly clean the rain 
collector several times a year. 

Note:

Cleaning the tipping bucket may cause false rain 
readings. See your Vantage Pro Console Manual for 
instructions on clearing weather data.

1. 

Separate the cone from the base by turning it 

counter-clockwise.

2.

Use soapy water and a soft cloth to remove any debris from the cone, cone screen, 
and tipping bucket. Watch out for spiders — they seem to like rain collectors!

3.

Use pipe cleaners to clear the funnel hole in the cone and drain screens in the base.

4.

When all parts are clean, rinse with clear water.

5.

Re-attach the cone and replace the debris screen.

Troubleshooting

If a Sensor Functions Intermittently

Carefully check all connections from the sensor to the ISS. See “Check SIM Sensor 
Connections” on page 4. 

Loose connections account for a large portion of potential problems. Connections should 
be firmly seated in receptacles, and plugged in straight. If you think a connection may be 
faulty, try jiggling the cable while looking at the display. If a reading appears intermittently 
on the display as you jiggle the cable, the connection is faulty. Try removing and then re-
installing the cable to correct the faulty connection. If the sensor still functions 
intermittently contact Davis Technical Support.

The Most Common Rain Collector Problem

If the rain collector seems to be under-reporting rainfall, remove the rain collector cone to 
clean the tipping bucket and clear out any debris.
