A yearly service on your weather station keeps sensors working accurately and reduces the chances of data gaps. If you think you may have a faulty sensor, first clean and then restart your system before contacting our Skyview support team.
Your anemometer should provide years of service. In some areas, however, spiders and insects can affect its operation. If wind speed seems low, use an allen key to loosen the setscrew on the side of the wind cups. Remove the wind cups, and clean the exposed portion of the shaft with a damp cloth or cotton swab. Clean the wind cups with water and a mild liquid detergent. Rinse thoroughly before replacing.
Do not use or add grease, oil, or a spray lubricant of any kind.
After replacing the wind cups and tightening the setscrew, check to make sure that the wind cups spin freely. If they do not, the bearings may be worn and need factory-replacement.
To ensure accurate wind direction readings, check the orientation of the wind vane annually. By default, the wind vane reports the correct wind direction if the anemometer arm points true north.
External Temperature / Humidity Sensors
Most temperature/humidity sensors do not need on-going maintenance but remember, sensors are weatherproof and not waterproof so sensors should not be submerged in water as this can cause water damage.
If you are concerned about dust build-up, particularly on your Davis Vantage Pro2 sensor, remove the lower portion of the cover by loosening the two screws. Using a clean, dry toothbrush, gently brush the gold mesh cloth. Clean the white plastic cover with water and a mild liquid detergent, and rinse thoroughly before replacing.
For greatest accuracy, we suggest you clean your rain gauge several times a year. Dust and debris can accumulate in the collection bucket on around the tipping mechanism, affecting its operation. Spiders and insects can make their homes in the base, and birds have been known to nest in the funnel.
To clean the rain collector, remove the funnel from the base. Gently clean the tipping-bucket and the funnel with water and a mild liquid detergent. Rinse thoroughly.
Leaf Wetness Sensors
Dirt and debris on the surface of the Davis DAV-6420 leaf wetness sensor can affect its accuracy. To clean the sensor, scrub its surface with a clean toothbrush, using water and a mild liquid detergent. Rinse well.
Solar Radiation Sensors
Dirt on the Davis DAV-6450 solar radiation sensor diffuser at the top of the sensor can affect its accuracy. As often as is practical, dust with a soft dry brush. When necessary, use a damp cloth or cotton swab to clean around the rim.
Dirt on the Davis DAV-6490 UV sensor diffuser at the top of the sensor can affect its accuracy. As often as is practical, dust with a soft dry brush. When necessary, use a cloth or cotton swab dampened with denatured alcohol to clean around the rim. Oil from your fingers can affect the accuracy of the readings. Do not touch the diffuser with your fingers or clean it with soap or detergent.
