ANEMOMETER
Issues
: Spiders and other insects can interfere with the
rotation of the cups or vane.
Solution
: If wind speed seems low or if wind direction
seems unusually static, use an Allen wrench to loosen the
setscrew on the side of the cups or vane. Remove the cups
or vane, and clean the exposed portion of the shaft with a
damp cloth or cotton swab. Clean the cups or vane with
water and a mild liquid detergent. Rinse thoroughly before
replacing.
After replacing the wind cups or vane and tightening the set
screw, check to make sure that the cups or vane spin freely.
If they do not, the bearings may be worn and need factory
repair.
Caution:
Do not use or add grease, oil, or a spray lubricant of
any kind.
INTEGRATED SENSOR SUITE (ISS)
Issue
: Console shows the message: LOW TX BATTERY
Solution: Replace the 3-volt lithium battery inside the
battery compartment on the underside of the ISS.
Note
: The message LOW CONSOLE BATTERIES indicates that
the C-cell batteries in the console need to be replaced.
Issue
: Solar panels look hazy
Solution
: Sunlight can make the solar panels look hazy or
cloudy. However, this haziness will not affect performance.
Keep the solar panels clear of snow, dust or debris for best
charging.
RADIATION SHIELD
Issue
: Excessive dirt and build-up on the plating can
hamper air flow.
Solution
: Wipe the edge of each ring with a damp cloth.
Issue
: Debris or insect nests can be caught inside the shield
Solution
: Check the radiation shield often for debris or
insect nests and clean when necessary. Disassemble and
thoroughly clean your radiation shield at least once a year.
See your ISS User Manual for detailed instructions.
OUTSIDE TEMPERATURE/HUMIDITY SENSOR
This sensor is located inside the radiation shield. While the
temperature/humidity sensor does not need on-going
maintenance, it is a good idea to remove dust when you
have access to it while performing a thorough cleaning of
the radiation shield
Issue
: Dust build up can interfere with air flow over the
sensor
Solution
: When you remove the plates of the radiation
shield, you will see a small white vented cover lined with
gold-covered mesh on the underside of the ISS. Using a
clean, dry toothbrush, gently remove any dust from the
cover. You can take off the cover and remove the mesh to
do a more thorough cleaning if necessary.
RAIN COLLECTOR
Issue
: Dust, debris such as leaves, insects, and bird
droppings can block the rain collector. Insect nests and
webs can prevent the tipping spoon from tipping. You
should clean the rain collector as often as needed, but at
least once a year.
Solution
: Remove and clean the debris screen. Use a soft,
damp cloth to remove any debris from the cone. Remove
the tipping spoon assembly on the underside of the ISS
below the rain cone by loosening the thumbscrew. Use a
damp, soft cloth to gently remove any debris, being careful
not to damage any moving parts or scratch the spoon.
When all parts are clean, rinse with clear water, and replace
tipping spoon assembly and debris screen.
Note
: Cleaning the tipping spoon may cause false rain
readings. You should clear the false data in the console after
cleaning
CONTACTING DAVIS TECHNICAL SUPPORT
Caution:
Never spray your sensor suite or any sensor with
insecticides. Insecticides can damage the sensors or even the
radiation shield.
