Troubleshooting: Cleaning the Radiation Shield

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.
