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.
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 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 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.
“The wind cups are spinning but my console displays 0 mph.”
The signal from the wind cups may not be making it back to the display. Remove
the cups from the anemometer (loosen the set screw). Put the cups back onto the
shaft and adjust them up or down 1/16 – 1/8 inch (1.5 – 3 mm). Check your cables
for visible nicks and cuts. Look for corrosion in the WIND connector on the SIM
and on splices in the cable. If using an extension cable, remove it and test using
only the anemometer cable. Contact Technical Support and ask for a wind test
cable if the problem has not been resolved.
Note:
If the anemometer is sending no data, the wind display indicates 0 speed and a North direction.
“The wind direction is stuck on north, or displays dashes.”
It is likely that there is a short or break somewhere between the wind vane and the
display. Check the cables for visible nicks and cuts. Look for corrosion in the
“WIND” jack on the SIM and on splices in the cable (if any). If possible, remove
any extensions and try it with the anemometer cable only. If none of these steps get
the wind direction working, contact Technical Support and ask for a wind test
cable.
