Note: 

For some models of the ISS, the order in which the five radiation shield plates are assembled may 
be slightly different than the order shown in the figure on page 25. For this reason, ensure that you 
always reassemble the plates in the same order in which they were disassembled.

4. Reassemble the plates in the same order in which they were disassembled, and fasten 

them together using a Phillips head screwdriver to tighten the 4” screws, as shown in 
the illustration.

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

Note: 

Cleaning the rain collector and tipping buckets my cause false rain readings. Unplug the RAIN sen-
sor from the SIM before cleaning so that no inaccurate readings are logged, or clear the weather 
data that was logged on the Vantage Pro2 console after cleaning is complete. See your Vantage 
Pro2 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. 

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.

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. To check for a faulty connection, 
try jiggling the cable while looking at the display. If a reading displays intermittently on 
the console as the cable is jiggled, the connection is faulty. Try removing and then re-
installing the cable to correct the faulty connection. If the sensor still functions intermit-
tently contact Technical Support. See “Contacting Davis Instruments” on page 27.
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. Make sure the cable tie around the 
tipping bucket has been cut and removed.
Most Common Anemometer Problems
“The anemometer head is tilted when I mount the anemometer.”

With the Allen wrench provided in the supplied hardware, loosen the screws 
holding the anemometer head on the arm. (The screws are on the bottom of the 
anemometer head, by the wind cups.) Turn the anemometer head so it is straight 
and then tighten the screws.
