Outside temperature sensor
reading seems too high Check calibration number and adjust if necessary. ISS or temp sen-
sor may need to be relocated. See ISS or other transmitter manual.
Inside temperature sensor
reading seems too high
Move the console out of direct sunlight. Make sure that the console
or sensor is not in contact with an exterior wall that heats up in sun-
light or when outside temperature rises. Make sure the console or
sensor is not near a heater or other internal heat source (lamps, ap-
pliances, etc.). Check calibration number and adjust if necessary.
Outside temperature seems
too low Check calibration number and adjust if necessary. Sprinklers may
be hitting the ISS radiation shield. Relocate. See ISS manual.
Inside temperature sensor
reading seems too low
Make sure the console or other temperature sensor is not in contact
with an exterior wall that cools down when outside temperature
drops. Make sure the console or other temperature sensor is not
near an air conditioning vent. Check calibration number and adjust
if necessary.

Inside humidity seems too
high or too low
Make sure the console is not near a humidifier or de-humidifier.
Check calibration number and adjust if necessary. If inside humidity
is low, and inside temperature is too high, see “inside temp” above.

Wind speed reading seems
too high or too low.
For low readings, remove the wind cups and check for friction sourc-
es. Check ISS location. Is it sheltered from the wind? See ISS man-
ual for additional wind speed troubleshooting information
Wind speed reads 0 either all
the time or intermittently
The problem may be with the anemometer. Test anemometer by
spinning wind cups. Check fields one-b and two-b on diagnostic
screen. May require call to tech support.

Direct
ion Wind direction reading is
dashed out
Wireless model - check reception. See Reception Problems below.
Cabled model - cable may be faulty.
If these steps do not reveal the problem, the anemometer may be
faulty. Call the factory for return authorization.
Wind direction always says
North Usually an ISS problem, especially if outside temperature is dashed
out as well. See the ISS manual for troubleshooting information
Ch
ill Wind chill reading seems too
high or too low
Check calibration numbers for temperature. Remember, wind chill
depends on temperature and wind speed. Make sure they’re work-
ing.

Heat Index reading seems
too high or too low
Check calibration numbers for temperature. Remember, the heat in-
dex depends on temperature and outside humidity. Make sure
they’re working.
De
w Dew Point reading seems
too high or too low
Check calibration numbers for temperature. Remember, dew point
depends on temperature and outside humidity. Make sure they’re
working.
Rain
No rain readings
Make sure cable-tie is removed from rain collector. See ISS manual.
If you are using wireless sensors from a Weather Monitor II or
Weather Wizard III, set the station type to SensorLink
