Troubleshooting

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 fas-

ten them together using a Phillips head screwdriver to tighten the 4" screws, as

shown in the illustration.

Cleaning the Rain Collector Cone

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 a soft, damp cloth to remove any debris from the cone, cone screen, and tip-

ping 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.

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. 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 sen-

sor still functions intermittently 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.
